I’m just going to say… “All” isn’t your feed. It is everything people on your instance have subscribed to. So, what you are saying is that the other people on the instance are subscribed to too much NSFW content. I’m not sure that individuals should get to police that.

“Subscribed” is your feed. Include or exclude whatever content you wish. You can blur NSFW if you want to browse all without seeing anything you don’t like.
