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’m a little curious: If you unsubscribe from something, does it disappear from your All? Or is it enough that a user in an instance was at some point or another subscribed?
All is the collection of communities that anyone on your instance is subscribed to. I believe once everyone unsubscribes, new posts are not automatically retrieved.
This is correct.
If you unsubscribe it will sit there with 0 subscribers, no longer being updated.
You have to go in with an admin account and purge the community to remove it.
