It probably exists in some obscure instance somewhere. I don’t like that kind of content though, so I won’t be looking for it and will be blocking it if it ever shows up in my feed.

Yeah, I joined VLemmy.net because they do not defederate with anyone and the admin made this post. Specifically the part where they said:

I feel it is important as many people have mentioned to “leave the power to the users” and let them decide the content they wish to see.

The great thing about the fediverse is that you can join a site that caters to what you want, or if it doesn’t exist you can make it yourself.

It’s easy to just block the things you don’t want to see. As long as the communities you use don’t allow that stuff, they will be banned if they bring it there. The same thing would have happened if more people joined those other reddit alternatives, but no one was willing to do it.
