Auto-moderate Instagram comments with Perspective API & Slack alerts

Automatically detects and hides hate speech/toxic comments, alerts your team, and logs flagged content for review.

Workflow Overview - Trigger: A Schedule node runs every 15 minutes to poll for new comments (Instagram doesn't natively push notifications easily, so polling is used). You could replace this with a Webhook if you set up Instagram webhooks via Graph API. - Scan Comments: Uses Instagram Graph API (via HTTP Request) to fetch recent posts and their comments. Assumes you have an Instagram Business Account and a valid access token (from Facebook Developer Portal). - Detect Toxicity: For each comment, it sends the text to Google's Perspective API (a free toxicity detection API; sign up at https://perspectiveapi.com/ for an API key). Threshold for "toxic" is set to >0.7 toxicity score (configurable). - Auto-Hide Offensive Ones: If toxic, uses Instagram API to hide the comment. - Alert Team: Sends a Slack notification (or email; configurable) with details. - Store Evidence: Appends the toxic comment details (text, user, score, timestamp) to a Google Sheet for auditing. - Error Handling: Basic error node to notify if API calls fail. - Business Value Alignment: This automates protection, reducing manual moderation and building trust.

Prerequisites: - n8n installed (self-hosted or cloud). - Instagram Graph API access token (set in n8n credentials or as environment variable). - Perspective API key (free tier available). - Slack webhook or email credentials. - Google Sheets API credentials (for storage).

How to Import 1. In n8n, go to the workflows list. 2. Click "Import from JSON" (or paste into a new workflow). 3. Update placeholders: - Replace YOURINSTAGRAMACCESSTOKEN with your token. - Replace YOURPERSPECTIVEAPIKEY with your key. - Set up credentials for HTTP Request (Instagram), Slack, and Google Sheets. - Adjust YOURINSTAGRAMBUSINESSACCOUNTID and YOURMEDIAID (or make it dynamic). 4. Test and activate.

If you encounter issues (e.g., API rate limits), adjust the schedule or add waits.

Notes on Customization - Looping: The "Loop Over Comments" uses SplitInBatches to process comments one by one, avoiding API rate limits. - Toxicity API: I used Perspective API as it's reliable and free for low volume. If you prefer another (e.g., Hugging Face), swap the HTTP Request body. - Instagram API: This fetches comments for the first recent post (simplified). To handle multiple posts, add another loop. - Alerts: Slack is used; change to Email node if preferred. - Storage: Google Sheets for simplicity; could be swapped for MongoDB or Airtable. - Sticky Notes: Three notes explain phases – they won't affect execution but help in the UI. - Testing: Start with test data. Instagram API requires app review for production.
