instagram-likes-deleter.js

/**
 * This script automates the process of deleting your own Instagram likes.
 * It deletes comments in batches to avoid hitting rate limits or breaking the page.
 *
 * WARNING: This function directly manipulates the DOM and depends on the current HTML
 *  structure of Instagram's website to work. If Instagram implements changes to the
 *  activity page layout, structure, or functionality, this script may break or cause
 *  unexpected behavior. Use at your own risk and always review code before running it.
 *
 * How to use:
 * 1. Navigate to the Instagram comments page by going to:
 *    https://www.instagram.com/your_activity/interactions/likes
 * 2. Open the developer console in your web browser:
 *    - Chrome/Firefox: Press Ctrl+Shift+J (Windows/Linux) or Cmd+Option+J (Mac)
 *    - Safari: Enable the Develop menu in Safari's Advanced preferences, then press Cmd+Option+C
 * 3. Copy and paste this entire script into the console and press Enter to run it.
 *
 * How to navigate to the comments page on instagram.com:
 * 1. Log in to Instagram on a desktop browser.
 * 2. Go to your profile by clicking on the profile icon at the bottom right.
 * 3. Click on "Your Activity" in the menu.
 * 4. Select "Interactions" and then "Likes".
 * 5. Follow the usage steps above to run this script.
 * IMPORTANT 1: You have to select English language for script to work properly (you can choose it on the bottom of the page)
 * IMPORTANT 2: If DELETION_BATCH_SIZE >= 10 or DELAY_BETWEEN_ACTIONS_MS <= 1000 went wrong message would appear after 100 unliked posts. 
 * NOTE: First two post is not unliked for a reason :) 
 * Just leave page open for 10+ hours. Script will restart each DELAY_BETWEEN_WENTWRONG_MS ms.
