I think the idea is that the NSFW servers also federate with nonNSFW. So I guess it solves the problem of seeing posts about the news when you want to browse porn?

488k is the number of posts, they have 19k followers. Pretty great news still tho

Yes! One of the main reasons lots of people use Beeper

As a side note, Ian betteridge, who has the law named after him for the phenomenon you reference, is quite active on the fediverse

The core premise of federation is that people have the right of association. It’s people core right to say ‘no we don’t want to federate with you’. The microblogging side of fedi has figured this mostly out at this point. Not sure why this is a big deal
