Delete all your Tweets for free.
The rate limit for the user timeline at X is 50 requests per 15 minutes at 20 posts per request. A script that loads the post itself would be able to delete 4,000 posts per hour in the best case.
TweetXer can delete around 17,500 posts per hour. https://www.youtube.com/watch?v=qlLKgjcUYu8
I started with a script that doesn't need the data export. It's still available, if you want to give it a try: https://gist.github.com/lucahammer/1aa16b4d3c1fb04035839da5ef699d65
I updated the script. You can now use it without the data export. But it is slow and unreliable.
Doesn't work for me! I see the bar but BEFORE i log in but it disappears after, and nothing.
I think we need a script like the one for Facebook where the deletion is automated and you watch the comments deleted in real time, no need to download anything besides the script.
