I can post to !cashless_society@nano.garden, no problem. But then when visiting nano.garden there is no Lemmy server there.
What I think is going on: nano.garden was once a Lemmy server that federated to Sopuli, Sopuli users subscribed, and then nano.garden ghosted us… disappeared. Yet posts can still be composed and old posts are still viewable locally. Participants carry on with the illusion that nano.garden exists.
Amiright? What are the consequences? Does this mean Sopuli users can only see new posts that come from other Sopuli users going forward?
That’s a really good idea, you could even add a warning when someone tries to post or comment after some length of time.
