Delete all your tweets without an API and for free

delete_all_tweets.js

// Delete ALL your tweets and un-retweet everything
// Just paste this code on the dev tools and leave the tab open. It deletes at [speed]. Make it faster or slower
// I don't know if Twitter has some internal safety to prevent a bunch of deletions from happening to fast, but at 100 it deletes 1000 tweets in under two minutes

// BEWARE you can't undo this action, and it will delete EVERYTHING

const speed = 100;

// do it on repeat. Timeouts are ugly but whatever, it works
