@BenA back in the day I used a browser plug-in (RedBlock, I think?) that would let you go to an account's list of followers, and block them all in like 30 seconds. Very satisfying.
Twitter later limited their API so the plug-in could only block 500 accounts at a time before you got locked out for the day, but I amassed a mighty block list before I abandoned ship.

I dunno. It's kind of fun blocking them one after another after another after another after another after another after another after another after another after another after another after another after another .....
