Description
Facebook Group Auto-Moderation
This workflow automatically monitors Facebook Group posts, analyzes them using AI, detects policy violations, logs incidents, notifies moderators and automatically hides high-severity posts to keep the community clean and safe.
This workflow listens to new Facebook Group posts in real time, processes each post individually and sends the post content to AI for moderation.If a post violates group rules (spam, scam, hate, adult content or aggressive promotion), the workflow alerts moderators, stores the violation in Airtable and automatically hides the post if the severity is high.
You receive:
- Real-time AI moderation of Facebook Group posts
- Automatic hiding of high-risk content
- Slack alerts for moderation actions
- Airtable logging for audit and tracking
Ideal for Facebook Group admins who want fast, consistent and automated moderation without manual review of every post.
