X Hygiene
Cleans up who you follow and who follows you on X, with ranked block and unfollow lists you approve yourself.
Problem
Over time your X followers fill up with bots and dead accounts, and your following list gets cluttered, but sorting it by hand is tedious.
Solution
It gives you a cost estimate first, then ranked block and unfollow lists with profile links. You set weekly, monthly, and per-run budgets, and it never acts on its own.
