Moderate Facebook group posts with OpenAI, Slack, and Airtable

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.

Quick Start – Implementation Steps

1. Connect the Facebook Group Webhook to your n8n instance.
2. Add your Facebook Page Access Token as an environment variable.
3. Connect OpenAI credentials for content moderation.
4. Configure Slack for alerts and Airtable for logging.
5. Test using sample Facebook post data.
6. Activate the workflow.

What It Does

This workflow automates Facebook Group moderation:

1. Receives new group posts via webhook.
2. Splits and processes posts one by one.
3. Normalizes post data (ID, message, user, time).
4. Sends post content to AI for moderation analysis.
5. Determines:

• Violation or not
• Category (spam, scam, hate, adult, etc.)
• Severity (low / medium / high)

1. Logs violations into Airtable.
2. Sends alerts to Slack.
3. Automatically hides posts marked as high severity.
4. Notifies the team whether auto-hide succeeded or failed.
