How do you manage to make your subs hidden before registration?
Is it default when using NSFW mark or there's smt special going on?
It's sure a killer feature for private teams who wants to have their own little space
Bonus: maybe you know, is there a way to make sure the community cannot be discovered and read without registration?
Default behavior for NSFW communities. It can be discovered still. Just can’t see any of the posts until subscribing. The behavior it seems you’d want would be done by running your own private instance with federation turned off.
