I think I’m going to add a mass-block to my Bitlbee plug-in for Mastodon: if you say “block X all” it will get status X, or the last status seen by X, get all the people who favorited it, and all the people you are currently blocking, and block all the people you are not already blocking. It feels pretty messed up to write such experimental stuff for an IRC based client written in C. Would a command line tool in Python be more useful to people? Would you use it?
