It's a decent bandaid, but I don't want to block all NSFW content, I just want better controls around it so I'm not fighting an onslaught of creative new community names around anal whenever I open the site or an app.
I could indeed join another instance, but figuring out which instances are federated to which other instances is a bit of a slog from a user perspective unless there's a big searchable graph available somewhere (which is entirely possible, I'm still very ignorant).
And who knows, maybe the apps will get better and be able to grab a local-only feed for each instance you have an account on and can patch together a feed from them all mixed together, and that would get me close to a workable solution for the long run.
How exactly would it put them in the line of fire? And how does defederating have anything to do with potentially being sued by Twitter?
