Why Are My Competition Entries Invalid? Every Cause and Fix (UK Guide)

▍Why Are My Competition Entries Invalid? Every Cause and Fix (UK Guide)

There's a particular kind of frustration in comping where everything feels right — you've entered hundreds of competitions, you've been consistent, you follow the rules — but the wins never come. In many of those cases, the entries themselves were invalid before they ever reached a winner draw. The promoter never even considered them.

Invalid entries are the silent killer of comping success. You don't get an error message. You don't get told. The entry simply gets skipped during winner verification and a different account is picked. This guide walks through every reason your competition entries might be invalid, in roughly the order each cause is encountered, with the specific fix for each one.

If the broader "I'm not winning anything" question is what brought you here, also read our companion post why am I not winning competitions: complete troubleshooting. This page is the deep dive on the invalid-entry slice of that problem.

▍What "invalid" actually means

First, some clarity. A competition entry can fail in three different ways, and only one of them is what we usually mean by "invalid":

1. Technical failure — the form didn't submit, the comment didn't post, the system errored. The entry never existed. You don't get charged for it but you also don't have one.
2. Disqualified — the entry was received but the promoter looked at it during winner verification and rejected it because something was wrong with you or your entry. This is what we mean by invalid.
3. Not selected — the entry was received, was perfectly valid, and just wasn't picked in the random draw. Normal comping reality.

This guide is about category 2: entries that made it to the promoter's pile but got removed before any winner draw. Promoters never tell you when this happens, which is why most compers don't realise how many of their entries are quietly invalid.

▍Cause 1: locked or private social media profiles

The overwhelming number-one cause of invalid entries on Instagram, Facebook, TikTok and X. If your profile is private — or has subtler restrictions like "hide from search" or "limit comments" — the promoter cannot verify the entry. They can't see your comment, your tag, your share or your follow. The entry gets skipped.

This applies even if the comp doesn't explicitly say "public accounts only". When verification happens (often by a third-party tool like Gleam or Easypromos, or a junior PR person manually picking), they need to see the entry. No visibility = no entry.

Subtler restrictions also matter:

• Shadow-bans from over-aggressive following/unfollowing or third-party automation
• "Hide from search" privacy settings (a one-time toggle most people forget about)
• Restricted comment settings that block comments from accounts that don't follow you
• Tag controls that block tags from non-friends
• Region-restricted accounts if you've set country-specific visibility

We wrote a deep guide on this — see social media account restrictions and comping — because it's such a common silent killer.

The fix: log out and visit your own Instagram, Facebook and X profiles via Google or an incognito window. If a stranger can't see your last 3 posts, your comments on brand pages, and the friends you tag, neither can the promoter. Set everything public, undo any hidden restrictions in privacy settings, and stop using third-party follow/unfollow apps.

▍Cause 2: duplicate entries (the auto-disqualifier)

Most UK competitions are strict about one entry per person. If you enter the same competition twice — even unintentionally because it appeared on two different aggregators — the promoter will typically:

• Disqualify both entries, not just the duplicate one
• Flag your account as potentially abusing the system
• Add you to an internal blocklist for the brand's future comps if it happens repeatedly

The trickiest part: you often don't know you've duplicated. The same comp might be listed on Sweepzy, in a Facebook group, and shared by a friend, with three slightly different URLs that all lead to the same Gleam form. Without a tracker, it's almost impossible to catch.

This is one of the main reasons our competition tracker checks for duplicates — it warns you before you submit a second entry to a comp you've already entered, even if it came from a different source. A Google Sheet works if you're disciplined, but most compers are not, and a single afternoon's missed logging is enough to start collecting duplicates.

The fix: track every entry within 60 seconds of making it, in whatever system you use. Set yourself a hard rule: no entry counts until it's logged.

▍Cause 3: entries from the wrong account

This comes up more than you'd think. Common variants:

• Entering on someone else's behalf — entering a comp for your husband, your mum, a friend. Almost always against the rules; the prize is awarded to the named account holder, who may not be you.
• Entering with a second account when only one per person is allowed. Even if you genuinely have two real accounts for different purposes, most comps treat that as duplicate behaviour from one human.
• Entering from a household member's account — strict T&Cs often exclude "family members in the same household" or "members of the same address".
• Entering with an account that doesn't match other details — you entered with email A but the social handle uses email B, so verification fails because the promoter can't link them.

The fix: pick one comping identity — one name, one email, one set of social handles — and use it consistently for everything. If you want to enter on a partner's behalf, that's their hobby, not yours.

▍Cause 4: missing a required action (follow, tag, hashtag)

Social comps usually require a sequence of actions, and missing even one invalidates the entry. The most common missed actions:

• Follow step skipped — you commented and tagged friends but forgot to follow the brand first. Most comps require following.
• Wrong number of friends tagged — comp says "tag 3 friends", you tagged 2. Invalid.
• Same friend tagged multiple times — "tag 3 different friends" not 3 mentions of one friend
• Used the wrong hashtag — comp requires #SummerWin2026, you used #Summer or #SummerWin (different)
• Forgot to repost / share / quote — comp requires reposting to your story, you only commented
• Tagged the wrong brand account — you tagged the parent company instead of the comp account, or you tagged a fan page
• Commented on the wrong post — easy to do if you scroll past the comp post quickly

For form-based comps, equivalents include skipping optional-looking fields that were actually required, not ticking the T&Cs box, or not completing the CAPTCHA.

The fix: before every social entry, re-read the requirements list. After every entry, do a 10-second verify — is the comment visible, did the follow register, is the hashtag spelled exactly as required? Most platforms let you edit the comment to fix a typo, but you can't add a missed follow retrospectively if the draw has happened.

▍Cause 5: entries from outside the UK or eligible region

Most UK competitions are explicit about geographic eligibility, and most compers either skim past or don't realise the implications. Common region rules:

If you're using a VPN that routes through another country, that can also flag your entry as ineligible — the form picks up your apparent location from the IP address, and if it doesn't match the address you typed, the entry can be auto-rejected.

The fix: read the eligibility line in the T&Cs before entering. If you're in NI, the Channel Islands or somewhere similar, get used to scanning specifically for your region. Turn off VPNs while comping.

▍Cause 6: ineligible by age, employment or recent winning history

Beyond region, common eligibility traps:

• Age 18+ for almost everything, and 25+ or 21+ for some travel/car/financial comps
• Employee and immediate-family exclusions — if you work for the brand, its PR agency, its advertising partner or even its delivery partner, you may be ineligible
• Recent winners — many brands have "no winner of a prize in the past 6 or 12 months from us" clauses, especially for big prizes
• Existing customer required — some loyalty-style comps are open only to existing customers, which is legal for non-prize-draw promotions
• Account age requirements — Instagram comps increasingly require accounts older than 30 days with a minimum follower count, to deter throwaway entries

Entering when ineligible doesn't get you in trouble per se, but it does mean the entry is invalid before the draw, and repeated behaviour can flag you.

The fix: a 10-second eligibility check before each entry. After a week it's automatic.

▍Cause 7: late entries (timezone confusion or early closes)

UK competitions usually close at 23:59 UK time on the stated closing date, but variations are common:

• Promoter-specified time that isn't midnight — "closes 5pm Friday" is more common than people realise
• Time zone in the T&Cs that isn't UK (a brand operating across markets may close at midnight Pacific Time, which is 8am UK)
• Early closes because the comp hit a maximum entry cap, the brand pulled the comp early due to issues, or the platform's clock differs slightly from yours
• Daylight saving boundary issues around late March and late October

An entry submitted even a minute after the closing time is invalid, full stop.

The fix: enter with a buffer. If a comp closes Friday 23:59, aim to enter by Thursday evening. Last-minute entries are the highest-risk for late invalidation. Set your tracker to flag closes 48 hours in advance, not on the day.

▍Cause 8: wrong entry method entirely

Some comps offer multiple entry methods (e.g. "comment on Instagram OR fill the form OR send a postcard") and others are method-specific. Picking the wrong method when only one is valid invalidates everything you did:

• Quote-tweeted on X when a retweet was required — these look similar but count differently
• Replied to a comment thread instead of the main comp post on Facebook
• Submitted via the email address rather than the form when the form was required
• Sent a postal entry to the old address in a magazine that recently changed offices
• Filled the form instead of doing the in-store entry when the comp specified in-store only

The fix: read the entry mechanic carefully, especially the verbs ("retweet", not "quote tweet"; "share", not "comment"; "post", not "reply"). When in doubt, do the most-public option.

▍Cause 9: brand-banned or restricted accounts

This one's harder to detect. If you've repeatedly violated a brand's comp rules — duplicate entries, ineligible region claims, suspicious behaviour, or formal complaints — you may end up on an internal blocklist for that brand's future comps. The brand doesn't tell you, you just stop appearing in winner pools.

This is rare but does happen, particularly with brands running comps on platforms like Easypromos, ViralSweep or Woobox that have built-in fraud detection systems. The platforms maintain shared blocklists across brands using their tools.

More common is being flagged by social platforms themselves — Instagram routinely shadow-bans accounts that comment-spam, follow-unfollow at scale, or use third-party automation tools. Shadow-banned accounts can still see comments but other people, including brand verification tools, may not see them.

The fix: stay clean. One entry per comp. Real engagement, not just comp comments. No third-party follow-bots. If you suspect a shadow-ban, search your own username on Instagram from a logged-out account — if you don't appear in suggestions for your own handle, you're shadow-banned. A 2-3 week cooldown usually clears it.

▍Cause 10: account too new or too thin

Increasingly common in 2025-2026: comps that auto-reject entries from accounts younger than X days or with fewer than Y followers, on the grounds that throwaway accounts are usually fraudulent.

If you set up a dedicated comping Instagram last week and started entering immediately, expect many of those entries to be silently invalid. Most comp platforms now check account age, post count and follower count as part of the fraud-detection signature, even if the comp itself doesn't mention these requirements.

The fix: if you're setting up a fresh comping account, build it for 30-60 days before relying on it for entries — post a few times, follow real accounts, build a genuine-looking presence. The cost is minor; the upside is real entries that count.

▍Cause 11: missing or malformed required fields

Forms can be fiddly. Common form-entry invalidations:

• Email format invalid — your email got auto-corrected by the browser, or you had a leading space
• Postcode format invalid — some forms reject "SW1A1AA" without the space, others reject "SW1A 1AA" with the space
• Phone number wrong format — international vs domestic, with or without leading zero
• T&Cs checkbox not ticked — easy to miss in a long form, fatal if missed
• CAPTCHA failed silently — modern "invisible" captchas can decide you're a bot without telling you
• Required field skipped because validation only highlighted the issue after submit
• Wrong age entered — you typed 1985 when you meant 1995, the form interpreted you as ineligible without flagging

The fix: look for an explicit confirmation page or email after every form submission. "Form submitted" is not the same as "entry accepted" — your entry is accepted when you get a confirmation. No confirmation = treat as invalid and try again.

▍Cause 12: AI-generated entries (the new auto-flag)

Increasingly important as of 2025-2026. Brands are starting to use AI-content detection on creative comp entries — slogans, photos, captions, tie-breakers. If your entry is flagged as AI-generated, it's auto-disqualified.

This matters even if you're entering legitimately. The detectors aren't always accurate, and overly-polished writing can flag false positives. If you wrote a tie-breaker yourself and asked ChatGPT to "tidy it up", that's enough to flag many detectors.

We've also seen photo comps reject submissions because they had EXIF data missing (a sign the photo was generated) or because the image triggered an AI-detection model. Real photos with proper metadata pass; AI-generated images mostly don't.

The fix: for creative comps, write tie-breakers yourself, take your own photos with a real camera (your phone is fine — it embeds EXIF metadata), and avoid letting AI "improve" your entries. If you must use AI for brainstorming, take the ideas and rewrite them in your own voice.

▍How to check if your entry was valid (after the fact)

You usually won't know. Promoters rarely tell you. But you can use these signals:

• Comment still visible from a logged-out view? Good sign for social comps.
• Confirmation email received? Good sign for forms.
• Entry shows in the third-party tool's "my entries" view (Gleam, Easypromos, Woobox all have this)? Strong positive.
• No reply to a query you sent the brand about whether your entry was received? Neutral — brands rarely confirm individually, but it's not necessarily a bad sign.
• You never see yourself listed in winner posts despite hundreds of entries to that brand? Possible blocklist signal — investigate.

The simplest single check: re-read your last 20 entries against this guide's checklist. If even 2-3 had clear issues, your average invalidation rate is probably 10-15%, which materially reduces your win chances.

▍Build the habit, not the fix

Most compers reading this guide will spot 1-2 causes they've been doing repeatedly. The fix isn't to chase each issue once — it's to build a 30-second verify routine after every entry that catches all of them at once:

1. Did I read the eligibility line? (Region, age, employment)
2. Did I do every required action in the right order? (Follow → tag → comment)
3. Have I entered this comp before? (Check the tracker)
4. Can I see the entry from a logged-out view? (Comment visible, form confirmed)
5. Did I log it in the tracker within 60 seconds?

Do that five-step check on every entry for two weeks and it becomes automatic. Your invalidation rate drops to near-zero and your effective entry count rises sharply without entering more comps.

▍A tracker fixes most of this

Most causes in this guide come down to two failure modes: you can't remember what you've already done (causing duplicates and missed verifications), and you can't see what you submitted (causing missed errors). A good competition tracker solves both — it logs every entry, warns about duplicates, surfaces closing-date reminders, and gives you a single dashboard of what's pending so you can spot patterns.

Create a free Sweepzy account — it's free forever, tracks unlimited entries, warns you about duplicates before you submit them, surfaces low-entry comps you'd miss elsewhere, and lets you batch-verify entries with a quick weekly scan. Most compers who switch from a spreadsheet to a real tracker cut their invalid-entry rate in half within a month.
