I'm not going to delete my X account, because I don't want the username reassigned. But I'm deleting all my follows and am starting to work on deleting posts. Turns out you can only unboost a post if you block the user, so a lot of y'all are going to be blocked. Don't take it personally. If anything, that's the kind of misinformation that makes X's data mining less useful.
@AlphaCentauri @th3j35t3r posted about this a few days ago:
1) Create a new Twitter account no identifying names etc.
2) Go to the account you're trying to obscure & change ur @/handle to make it available.
3). QUICKLY Go to the new account and change it's @/handle to ur original @/handle
4). Deactivate your original account.
Eventually your original data will cycle out of their backups & nobody can take your handle.
