When bad comments arrive by the hundred, deleting them one by one stops working. Start with Instagram's own free tools: filter offensive comments automatically, add your own word list, limit comments from new accounts during a spike, and remove up to 25 comments at once. Then watch for the trap: keyword filters also hide real buyers. Once you're past a few hundred comments a day or running ads, automated moderation that reads what each comment means is the only way to keep up without hiding customers.
First, sort what you're actually dealing with
Not every "bad" comment needs the same action. Use this table:
| Comment type | Example | What to do |
|---|---|---|
| Scam or phishing | "Claim your prize, DM @brand_support_team" | Hide, then delete and block if it impersonates you |
| Bot or engagement bait | "Check my page 🔥🔥", emoji strings | Hide |
| Hate or harassment | Slurs, personal attacks | Hide or delete, restrict or block the account |
| Negative but genuine | "Mine arrived broken" | Keep and reply. Hiding real complaints makes things worse. |
| Buyer question | "Price?", "Do you ship to Canada?" | Reply fast |
| Praise | "Love this!" | Like it, reply if you have time |
In our own study of 6,519 comments on one brand account, 25% were spam, 2.9% showed buying intent, and 83% of those buyer comments went unanswered for more than a day. The problem is rarely just the spam. It's the buyers hiding inside it.

The keyword trap: filters hide buyers too
Keyword lists can't tell intent. The phrase "DM me" appears in scam comments ("DM me to earn $500 a day") and in buyer comments ("Price? DM me please"). "Link?" can be a bot or a shopper. Block those words and you hide the people you most want to reach.
Two rules keep a word list safe:
- Only add words that never appear in a real customer's comment, like crypto terms, fake giveaway phrases, or your known impersonator handles.
- Check your hidden comments once a day for buyers who got caught, and unhide them. Buyer questions are short and plain, and at a glance they look a lot like spam.
A 15-minute daily routine that holds up to a few hundred comments
- Minutes 1 to 5: open the post with the most new comments. Answer every buyer question first.
- Minutes 5 to 10: bulk delete the obvious spam, 25 at a time, and restrict or block repeat accounts.
- Minutes 10 to 15: check your hidden comments folder for buyers the filters caught, and add any new scam phrases to your list.
If this routine takes longer than 15 minutes, or you're running ads, the volume has outgrown manual moderation.
