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?
If you unsubscribe it will sit there with 0 subscribers, no longer being updated.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.
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.
