Lemmy.ml, the most popular instance fo Lemmy out there, is not accessible in my country unless I use a VPN. But, I can subscribe to any community that exists on lemmy.ml from here and even post on those communities from this account.
I love this aspect of Lemmy.
Are you sure? If the government here in NZ blocks Lemmygrad (IIRC hosted in Switzerland) would that stop my home instance (Beehaw which I think is hosted in the USA) from being able to access Lemmygrad posts?
No, it wouldn’t. The Beehaw server is located in the United States. External communities aren’t retrieved via your machine, but via their server.
