How to Bulk Delete Facebook Comments (Spam & Trolls)

Why spam comments pile up faster than you can clean them

A single Facebook ad with strong reach can attract hundreds of spam comments - fake giveaways, scam links, competitor trolling, and bot replies - within hours. Left unchecked, they bury real customer questions, lower trust, and quietly waste ad spend by making your offer look sketchy. The problem is that Facebook gives you no native "select all and delete" button, so manual cleanup doesn't scale.

There are two ways to deal with it: clean up by hand, or automate moderation so spam never stays visible.

Manual deletion vs hiding - what's the difference

Facebook gives you two actions on a comment, and they behave differently:

• Hide - the comment stays visible to the author and their friends but disappears for everyone else. The spammer doesn't realize they've been moderated, so they don't retaliate or repost. This is the safest default for spam.
• Delete - the comment is removed entirely. Use this for scam links and abuse you want gone for good. It's irreversible.
• Block - stops the author from commenting again, useful for repeat offenders and bot accounts.

For most ad spam, hiding is the smart move because it's invisible to the troll.

Cleaning up comments manually

1. Open the post or ad in Meta Business Suite or Ads Manager.
2. Go to the comments/activity view for that post.
3. Click the menu on each comment and choose Hide, Delete, or Block.
4. Repeat for every comment - there's no multi-select, so this is one-by-one.

This works for a handful of comments, but on a busy ad it's a full-time job, and spam reappears the moment you stop watching.

Automated keyword-based moderation

Instead of reacting after the damage is done, set rules that act the instant a comment is posted. With AFP.MONSTER you build a keyword list of spam triggers - links, profanity, competitor names, scam phrases - and assign an action (hide, delete, or block) that runs automatically across all your posts and ads.

Setup is fast:

1. Connect your Facebook Page (and Instagram, if you run cross-platform).
2. Create a keyword list with the words and patterns to catch - for example http, whatsapp, free money, or specific scam handles.
3. Choose the action: hide spam quietly, delete scam links, or block repeat offenders.
4. Use the visual workflow builder to combine rules - e.g. hide on link detection, block after a second offense.
5. Turn it on. New matching comments are moderated within seconds, 24/7.

Because rules apply across every connected post, you protect new ads automatically without touching each campaign. Your whole team workspace shares the same keyword lists, so moderation stays consistent.

A practical moderation strategy

• Start by hiding rather than deleting - it's reversible and invisible to spammers.
• Keep one keyword list for links/scams and another for profanity, so you can tune them independently.
• Review hidden comments weekly to catch false positives and refine your keywords.
• Reserve block for accounts that keep coming back.

Combine a one-time manual sweep of existing spam with always-on keyword automation, and your comment sections stay clean - without you watching every post.
