Apologies for yet more dumb questions. Not sure if it’s a Thunder thing or a Lemmy thing.
When I go to search for new communities, I only get the option now to search within the instance I signed up on (Aussie.zone) instead of everywhere. Have I accidentally changed a setting somewhere?
Your local instance search will return communities from other instances if somebody on your instance already subscribes to them.
As others already pointed out, search for the whole URL otherwise.
AHH!!! NOW! THAT’S interesting! How curious!!! What a whacky phenomenon!
So in theory, if I set up a new account and subscribed to all 26k communities, (made up number) then everyone else on ‘my’ instance could see them too!
Yes.
I even saw scripts which mass subscribe to popular communities to populate new instances.
