The local copies cease to exist online. Remote copies on other instances stay. There's a number of communities I subscribed to that no longer exist independently, but which I can still see on my old instance, for example.
Are they dependamt on the cache some users actively purge or are they stored indefinitely (assuming they had no interaction beyond a view).
I don't actually know the answer to that one. I'd guess it's permanent, though. That being said, Lemmy's been built on a lot since I last looked at the source code.
They are stored until the instance admin(s) choose to purge the community. Then all posts from the community will be purged from the instance.
