It's a fair point that extensions like these can be abused with false reports, but these aren't like police reports, these are just sharing that they didn't want that user in their server and banned them. So if you trusted the admins/mods of that server you could automatically just prevent that person coming in to yours.
Weirdly, there is similar thing on reddit to deal with trolls (which has been around for years) where, if say you get banned on one subreddit that's shared with other subreddits and you're automatically banned there too. Even though reddit itself hasn't actually given you like a site wide ban.
I'm not saying these kind of ban lists are a great idea but there is a double standard here. Even leftists on twitter (before Musk bought it) were proud of maintaining blocklists, so that they could preemptively block those that disagreed with their politics (and keep their little echochambers intact). That's faggy shit, but you could argue they have the right to do it.
