TIL .world blocks more communities than I though.

I mean, I don't agree with everything dbzer0 (the instance) stands for, but it stands for freedom of speech and I'm with that.

It sounds like you want an account on dbzer0. You don't need to give up your .world account or leave .world; the nice thing about federation is you can actually be on multiple instances. It's kind of pointless in a way, but if your instance does something you don't like, you can still federate through another instance. dbzer0 is my main/home instance (I have one other because I was PieFed-curious), but for .world and other bigger instance users, it's a good side instance to keep an account with.

Another instance of all of this is that most instances defederate from the NSFW instance, so if you make an account there, your access to NSFW content is ensured. (Most defederate them for a good reason. I've never seen them post straight up CSAM, but they post stuff that blurs the lines. I think (and want to believe) they're on the legal side, but I believe the confusion and questionable nature is intentional. Which is why some instances have defederated them, in case they cross that line (or maybe they have before).
