Remove Duplicate Comments From an Instagram Giveaway (One Entry Per Person)
Most Instagram giveaways run on an unspoken assumption: one comment, one entry. The problem is that nothing stops someone from commenting the same thing ten times, and on a busy post, that's exactly what happens. Here's how to make "one entry per person" an actual rule instead of a hopeful guideline.
Quick Answer
Turn on "Remove duplicate users" on InstaPicker's comment picker before you draw. It keeps one entry per unique commenter and drops any repeat comments from the same account, so posting ten times instead of once doesn't improve anyone's odds.
Should Multiple Comments Count? Pros and Cons
Before assuming "one entry per person" is the obvious choice, it's worth knowing why some hosts do the opposite on purpose.
Allowing multiple entries per person can boost raw comment count, which helps a post's reach through Instagram's engagement signals. The downside is real: it rewards whoever has the most free time to spam comments, not whoever actually cares about the prize, and it looks unfair to anyone who only commented once.
One entry per person is fairer and far easier to defend if anyone questions the result, at some cost to raw comment volume. For almost every giveaway, this is the right default — the exception is a case where you've explicitly designed a mechanic that rewards repeat engagement (which should be stated very clearly, since most entrants will assume one-per-person is standard).
Wording the Rule in Your Caption
Say it plainly, and say what happens to extra comments, not just that duplicates "don't count":
❌ Vague: "Comment to enter!"
✅ Clear: "Comment to enter — one entry per person. If you comment more than once, only your first comment counts toward the draw."
The second version heads off a common complaint: someone who commented five times assuming each one was a separate chance. Stating upfront that only the first counts avoids an argument after the fact. If you want this wording built into a full rules document rather than just the caption, the Giveaway Rules Generator can produce one you host and link to.
Removing Duplicates in the Picker
- Paste your post or Reel link into the comment picker.
- Turn on Remove duplicate users in the Giveaway Rules & Filters section.
- Set any other filters your caption promised (required mention, minimum comment length, excluded words).
- Press Scrape Comments & Pick Winners. The tool loads every comment, then collapses repeat commenters down to a single entry each before applying your other filters.
- Check the eligible count the tool reports — it should now reflect unique qualifying commenters, not raw comment volume.
This one toggle handles the most common duplicate problem (the same person commenting the exact same thing, or different things, multiple times) without you manually scanning for repeat usernames. It works the same way whether you're drawing from a regular post or picking a winner from Instagram comments on a Reel.
Edge Cases: Replies, Edited Comments, Multiple Accounts
The duplicate filter catches repeat comments from the same username, but a few situations sit outside what any automated filter can fully resolve:
Replies counted separately from top-level comments. If your rules allow both a top-level comment and a reply to count, and the same person leaves one of each, decide explicitly whether that counts as one entry or two, and state it. The duplicate filter treats repeat comments from one username as duplicates regardless of whether they're top-level or replies, so this is usually already handled correctly — just be clear in your caption about which comment types are eligible at all.
Edited comments. Someone editing their own comment after posting doesn't create a duplicate; it's still the same comment from the same account. You don't need to worry about this separately.
Multiple accounts, same person. This is the one no automated filter can catch. If someone comments from two different Instagram accounts they personally control, each account looks like a distinct, legitimate commenter to any tool, including this one. There's no reliable automatic way to detect this. The practical response is to state in your rules that entering from multiple accounts is against the rules and grounds for disqualification if discovered, which at least gives you a basis to act if it's reported or obvious (for example, two accounts with near-identical usernames or profile photos).
Frequently Asked Questions
Only if the host explicitly allows multiple entries per person, which most giveaways don't. With InstaPicker's "Remove duplicate users" filter turned on, repeat comments from the same account are collapsed into a single entry, so commenting ten times gives the same odds as commenting once.
A duplicate filter identifies comments from the same username and keeps only one of them (typically the first) as the eligible entry, discarding the rest before the draw runs. This applies regardless of whether the repeat comments are identical text or different each time.
Most giveaways say no, even in this case, since it still amounts to one person improving their own odds through repetition rather than reach. If you do want to allow it, state that explicitly and separately from your general entry rule, since entrants will otherwise assume standard one-per-person applies.
No. This is outside what any automated tool, including this one, can detect — two different usernames look like two different people to any picker. State in your rules that multi-account entries are against the rules, so you have a basis to disqualify if it becomes obvious or gets reported.
InstaPicker keeps one eligible entry per unique commenter when the filter is on. If you need a specific one of several comments from the same person to be the one considered (for instance, the one that actually followed all the rules), check the comment text yourself for any borderline cases before finalizing the draw.
