Who is this for?

This n8n workflow is designed for Facebook Page administrators, social media managers, and community moderators who want to automate comment management on their Facebook Pages. It's perfect for businesses with high comment volume, content creators, and marketing teams who need to maintain a positive community environment without manually reviewing every comment. The workflow automatically filters and responds to positive/supportive comments while handling negative ones appropriately.

What this Workflow Does

This n8n workflow monitors Facebook Page comments, classifies them using OpenAI, automatically responds to positive and supportive comments, and handles negative comments by deleting them and tracking repeat offenders. It can ban users who repeatedly post negative content and maintains a record of all interactions in Google Sheets.

  • AI-Powered Classification: Uses OpenAI to classify comments into positive, supportive, or negative categories
  • Intelligent Response Generation: Creates human-like replies in the same language as the original comment (English or Bangla)
  • Negative Comment Management: Deletes negative comments and tracks them in Google Sheets
  • User Banning System: Automatically bans users who repeatedly post negative content
