Facebook Profanity Filter and Blocked Words Guide

Profanity filter versus blocked words

The profanity filter is Facebook’s general offensive-language layer. The blocked-word list is controlled by the Page and covers the exact terms and patterns your brand chooses. Use the profanity filter for a broad baseline, then add custom keywords for recurring scams, impersonation, harassment, and campaign-specific spam.

Meta’s profanity-filter help says flagged comments remain visible to the author and their friends but not to everyone else. That is hiding behavior, not deletion.

How to turn on the Facebook Page profanity filter

1. Log in, switch into the Page, and open Settings and privacy.

2. Open Settings, then Followers and public content.

3. Find Hide posts and comments with profanity.

4. Turn the setting on.

5. Review the hidden-comment queue after activation to understand what the filter catches for your audience.

How to add blocked words

Meta’s current blocked-words instructions allow people with Facebook access to a Page to add up to 1,000 keywords in any language, including words, phrases, and emojis. Meta also hides common variations such as misspellings, plurals, abbreviations, and symbol substitutions.

1. Open the Page’s Followers and public content settings.

2. Choose the control for hiding comments that contain certain words.

3. Enter terms separated as the interface requests, or upload a CSV when available.

4. Review the automatically detected variations rather than duplicating all of them manually.

5. Save, then test the list against real comments and likely false positives.

What belongs on the list

• Known scam contact details, wallet-recovery language, and fake support phrases.

• Malicious domains and recurring promotional links.

• Explicit slurs, threats, and abusive phrases that have no legitimate product meaning.

• Follower-selling, unsolicited promotion, and bot phrases repeatedly seen on the Page.

• Campaign-specific attack language confirmed by the moderation team.

What not to block automatically

Avoid broad commercial terms such as ‘price,’ ‘refund,’ ‘scam,’ ‘cancel,’ competitor names, or product ingredients unless the surrounding context is consistently harmful. A shopper asking ‘Is this a scam?’ is exposing a trust objection the brand should answer. A customer requesting a refund needs support, not silent removal.

A starter review policy

• Add a term only after it appears as harmful content more than once, unless the risk is obvious.

• Assign an owner and review date to each campaign-specific keyword.

• Audit hidden comments weekly for legitimate demand and language drift.

• Remove terms with repeated false positives.

• Maintain separate market notes for slang and multilingual campaigns.

• Pair keyword rules with contextual review for ambiguous comments.

Why a filter is only the first layer

Filters can remove familiar noise, but they cannot answer the clean comments left behind. Paid ad threads still contain shipping questions, objections, support issues, and high-intent buyers. The operating layer needs to decide whether to reply, move to Messenger, or escalate—and preserve the result.
