How to Stop Spam Comments on Facebook (2026)
Facebook has no single anti-spam switch, but several of its tools work together. Moderation Assist hides comments by what they contain and by who wrote them, such as accounts less than a week old. The Page's word list and profanity filter hide the words you name. Blocking keeps repeat spammers off the Page. Meta says the word filters and Moderation Assist also cover ads from your Page, so one setup works for posts and ads. What none of them does is read what a comment means, so spam that avoids your words still gets through.

How do you stop spam comments on Facebook?
Use Moderation Assist to hide comments with links or from new or suspected fake accounts, list your spam words in Page settings, and block repeat spammers.
Set Moderation Assist to catch spam accounts and links
Meta's automatic rules, by who wrote a comment or what it contains. They cover your Page, profile and the ads you run.
- 1
Open Moderation Assist
Switch into your Page, then go to Professional dashboard > Engagement > Tools > Moderation Assist and tap Add in the Manage comments section.
- 2
Add the criteria that catch spam
For bot waves, use the author criteria: a Facebook account less than 1 week old, no profile picture, no friends or followers, at least 3 comments reported, deleted or hidden by an admin in the past 30 days, or may be using a fake identity. For link spam, A link to a specific site is narrower than A link. Confirm with Add to Moderation Assist.

Check the Activity Log
Engagement > Tools > Activity log shows the hidden comments and the criteria they met. Search by commenter or filter by criteria, and tap Undo to show a comment again.
Block spam words on your Page and its ads
Two Page settings that hide comments with words you list or with profanity, on your posts and on ads from the Page.
- 1
Open the Page's settings
Switch into your Page, click its profile photo, then Settings & privacy > Settings > Followers and public content.
- 2
Add your spam words
Click Hide comments containing certain words from your Page. Add words, phrases or emojis separated by commas, paste a list or upload a .CSV. Up to 1,000 keywords; Facebook also hides misspellings, plurals and versions with numbers or symbols, and these don't count toward the limit.
- 3
Turn on the profanity filter
On the same page, toggle Hide posts and comments with profanity. Facebook decides what to hide from the words and phrases people most often report as offensive.
Remove what gets through and block repeat spammers
For spam that is already posted, on Page posts and on ads.
- 1
Clear it from Page posts
Next to the comment, hover over Options and click Hide comment, or Delete to remove it from the post. Report comment is in the same menu, for spam that breaks Facebook's Community Standards.
- 2
Clear it from ads
In Ads Manager, open the Ads tab, click Edit below the ad's name, then … next to the name > More options > Manage Facebook comments. On each comment, open … > Hide comment or Report comment.
- 3
Block repeat spammers
Go to Settings & privacy > Settings > Blocking and block the profile, selecting Ban [user] and new profiles they may create. You can also hover over the commenter's photo on your post and choose Block.
Hide spam by meaning with a tool on Meta's API
How third-party tools catch the spam that word lists and rules miss, on Page posts and ads.
- 1
Connect the Page
The tool connects through Meta's login, and someone who can moderate the Page grants it permission to read and manage comments.
- 2
Receive new comments, ads included
Meta's Page webhook reports new comments as they're written. It covers comments on ad posts too, though not the ad posts themselves.
- 3
Judge each comment and hide the spam
The tool reads what the comment says and hides spam through the API. The same setting unhides it, so a comment hidden by mistake can be brought back.
What can't Facebook do on its own?
Facebook's filters match words, links and account signals, not meaning, so a scam reply with no link and none of your keywords gets through.
- Moderation Assist only hides comments posted after you add a criterion. Spam that was already there stays until you remove it.
- Broad criteria catch customers too: A link or An image also hides a buyer who shares a link or a photo.
- Moderation Assist's profanity criterion covers eight languages: English, Spanish, Portuguese, French, Japanese, Italian, Arabic and Russian.
- Hidden spam stays visible to its writer and their friends, and Meta notes that blocking may not catch all the new accounts a spammer creates.
- Ads Manager handles ad comments one at a time, and the filters don't answer the real questions posted next to the spam.
How do you stop Facebook spam comments automatically?
RYPL's AI reads new comments on your Page and ads as they arrive and hides spam, scams and hate by what they mean, within seconds.
- Spam is spotted in about 1.7 seconds on average, by RYPL's own measurement. On Facebook, half of the comments RYPL hid automatically were gone within 13 seconds of being posted and 94% within a minute (RYPL's own measurement, September 2026).
- Comments are judged by meaning, so a scam reply that avoids your keywords can still be caught. Hidden comments can be unhidden.
- Banned words and author blocking on all plans, up to 50 words per channel: scam matches words that start with it, *scam* matches it anywhere, and "scam" in quotes matches only the whole word.
- From Pro, moderation rules in plain words, with review first if you want to check matches before a rule acts. Complaints go to a Needs attention queue for a person, and real questions get an answer from your knowledge base.
