By the way, if you are starting up your own fediverse server, it may be tempting to blindly copy someone else’s block list, but some corners of the fediverse have been a bit over eager with full instance bans, in my opinion, which tends to break the whole federation model (imagine if you couldn’t email anyone with a certain university’s email domain because your email provider disagrees with the university policies).

If an instance is putting a lot of irritating stuff in your server’s global timeline, it might be better to just mute them from the global timeline.
