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 In n8n, go to the workflows list. Click "Import from JSON" (or paste into a new workflow). Update placeholders: Replace YOUR_INSTAGRAM_ACCESS_TOKEN with your token. Replace YOUR_PERSPECTIVE_API_KEY with your key. Set up credentials for HTTP Request (Instagram), Slack, and Google Sheets. Adjust YOUR_INSTAGRAM_BUSINESS_ACCOUNT_ID and YOUR_MEDIA_ID (or make it dynamic). 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.
