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.
It’s tedious, but I found just looking at lists of communities to be more helpful. If something looks interesting, open it up, check it out, and subscribe. Browsing your subscribed communities is an infinitely better experience. Plus, if you’re willing to take the time blocking communities, I feel like that takes just as much time as scrolling through a list of ones for potential matches for your interests.
