I deleted all tweets, but they still show up!
You just deleted them from the surface, but they are still in your Twitter Archive!
Do you know what Twitter Archive is? Twitter (X) keeps a record of your tweets, followers, lists, and many other things in your Twitter Archive. You can always access and download your Twitter archive ⬇️ and see what you had in your Twitter past!
When you delete a tweet from Twitter, it still exists in your archive. So, you need to delete them from your Twitter Archive. There is a "tweets.js" file there. It has all your past tweets!
If you use Circleboom and delete your Twitter archive, you can delete tweets permanently, and they won't reappear!
