So, how many lemmynsfw.com communities have you blocked?
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.
I blocked the whole instance. I'll admit that I do want to see nude females (who are obviously adults) but I was seeing lots of other stuff that I don't find sexy, and blocking specific communities was like playing whack-a-mole.
