I think this, especially the second issue, is something the Fediverse (Lemmy in particular) will have to work through at some point.
If Reddit bans a subreddit on a controversial subject, it’s banned, it’s gone. But if a Lemmy instance defederates with another instance for hosting controversial content, you just find another instance that doesn’t.
I think the real issue is with federation in general and the creation of bubbles: there is a certain subset of users who just want full federation and full visibility, including sites that host lolicon, fascism, and other problematic content. Even if they aren’t, say, fascists themselves, but just free-speech absolutists. The issue is that any instance that doesn’t defederate with, say, Fascist instances, is tainted, either by association (“this instance refused to defederate from fascist instances, so we’re defederating from them too”) or because problem users are attracted to it (“people in our comment sections from this instance have been defending fascism, so we’re defederating to keep them out”).
And there really isn’t a good solution to the issue, aside from hosting your own tiny client-only server.

A friend of mine just opened up the Spanish teacher’s tower while she was out of the room and stole her RAM. He was in IT and was the student assigned to try and fix it too, which was hilarious.
