I just reached 112 myself.
I’m very much awaiting a time when users can block specific instances. I still don’t want to check the option to hide NSFW content, because I do want to see NSFW content that may show up on non-porn communities. Just not really interested in seeing so much porn in All.
You can check on your settings page, btw, in the Blocks tab - count quickly with Ctrl+F.
Almost none. I browse all almost exclusively and have nsfw enabled, but none of the communities really bother me enough to block them. I just scroll past the stuff that I don’t have any interest in, same as sfw content.
