Well, if what you want are massive ways to delete tweets, I will present you with 4 applications that are usually very effective. But first, I want to highlight some important observations that you have to know:
Twitter does not recommend the use of this type of tool, mainly due to the temporary blocking that they can cause in your profile during the process. The network Clipping Path Service recommends creating a new account with a temporary user, changing your old user and updating the new account for the user you had (although it's not practical at all, not to mention that you lose all your followers and your direct messages).
Before deleting your tweets, you should ideally make a backup of your account . Go to "Settings and privacy", then "Account", scroll to the bottom and click "Request your file". With this, you will receive a history of all your posts by email.
All apps that mass-delete tweets only manage to delete the most recent 3,200 tweets from your profile. This is a limitation of Twitter itself, which also limits the display of your tweets to that number on any other platform. To delete all the tweets from your account with this type of tool, you must repeat the process as many times as necessary. If you have 32 thousand tweets, for example, you must repeat the process 10 times.
