idea: let each instance have a prepopulated blocklist

let the admins of each instance have a list of blocked users that gets inherited to members of that instance, but let users remove from that list as well as add to avoid abuse. and don't hide the comments from these users, just collapse them to let people know a comment has been hidden in case of mistakes

(possibly even allow regex to avoid RandomWord1234, which was common on reddit)

this is a rather extreme tactic though, only for if spam becomes overwhelming

Is there an equivalent of "going dark" in lemmy? Like if there is some "global" or "fediverse" issue that communities want to protest, is there the same option as back on Reddit that they are using now?
