What is Comment Guardian?

Comment Guardian is a brand protection agent that monitors Facebook Page comments every 4 hours, classifies each as legitimate, suspicious, spam, phishing, or impersonation using AI, and auto-hides dangerous comments based on your configured rules. It supports three modes: monitor-only, approve-first, and auto-hide. Built for social media managers and brand safety teams.

Why this kit exists

The problem — and how this kit solves it.

The Problem

Facebook Page comments are a magnet for spam, phishing links, and impersonators. A single "Contact us at +1-800-FAKE" comment on a popular post can redirect customers to scammers. Manual moderation does not scale — high-volume pages get hundreds of comments daily, and threats hide among legitimate engagement.

The Solution

This agent scans your Facebook Page comments every 4 hours and classifies each into 5 categories: legitimate, suspicious, spam, phishing, or impersonation. Three operating modes give you control: monitor-only (alerts without action), approve-first (flags for review), or auto-hide (automatically hides comments matching configured classifications — spam and phishing by default). A keyword watchlist adds custom detection rules. All actions are logged and sent via Slack alerts.

The Outcome

Remove spam and phishing comments from your Facebook Page within 4 hours of posting, before they reach your audience.

Who is this for?

Social media managersBrand safety teamsCommunity managersAgency teams
1

Social media manager for a high-volume brand page

Auto-hide spam and phishing comments on posts that get hundreds of comments. The agent handles the volume while you focus on genuine community engagement.

2

Brand safety team at a regulated company

Use approve-first mode to flag suspicious comments for human review before action. Maintain compliance requirements while catching threats at the 4-hour interval.

3

Agency managing multiple client Pages

Deploy Comment Guardian per client Page. Each sends Slack alerts to the relevant channel. Auto-hide keeps client pages clean between your moderation shifts.

Frequently asked questions

Comments are classified as: legitimate (normal engagement), suspicious (potentially problematic but unclear), spam (promotional junk or bot content), phishing (links or contact info designed to steal credentials or redirect customers), or impersonation (someone pretending to be your brand or staff in comments).

Monitor-only sends alerts but takes no action on comments. Approve-first flags comments and waits for your approval before hiding. Auto-hide immediately hides comments matching your configured classifications (spam and phishing by default). You can switch modes at any time.

Yes. The default auto-hide classifications are spam and phishing. You can add impersonation and suspicious to the auto-hide list, or remove categories. The keyword watchlist lets you add custom terms that always trigger flagging regardless of AI classification.

A typical result: "Scanned 47 comments, flagged 5 (2 auto-hidden). 1 phishing ('Contact us at +1-800-FAKE'), 1 impersonation, 3 spam." Each flagged comment shows the original text, classification, and action taken.

No. Comment Guardian monitors Facebook Page comments only. It requires a Facebook Page ID during setup and uses the Meta Graph API for comment access.
