I like the BlueSky feature of "Starter Packs," where people can make a list of accounts they like, and with one click you can follow them all.
But it's absolutely insane that you can't *remove* yourself from somebody else's list.
People are making "Starter Packs" of accounts to harass and sharing them with their followers.
They really need to add a built-in way to find out which lists you've been added to, as well as a way to remove yourself (and report the list) if they're malicious.
