I specifically chose my instance by what content they did and didn't choose to block. I turned away from several otherwise appealing instances because they didn't block some of the content I would've wanted them to. I know I can do it myself, and I do when I need to, but I want an instance that aligns with my interests enough that I don't have to worry about blocking every problematic group as they pop up. If something changes and the instance ends up blocking things I wouldn't want blocked, I move to another instance. It's as easy as moving to another seat on the bus - barely an inconvenience.
