How do communities work across servers? For instance, I registered my account on server A, and create a community named MyCommunity on Server A. Someone who’s registered on Server B can access MyCommunity by going to !MyCommunity@ServerA.
Now if someone else on Server B decides to create a community also called MyCommunity on Server B, I could access that by going to !MyCommunity@ServerB.
My question is, with the MyCommunity communities ever sync across Server A and Server B? Or will they remain completely separated since they’re on different servers? Will things posted to !MyCommunity@ServerA ever show up for people that have only subscribed to !MyCommunity@ServerB, or are these kept completely separate?
To be fair, my understanding of the entire internet is that the entire point is that they remain separate. They can sync on their own if they wanna, but they are still separate instances organizationally and logically, as they should.
After all, if that was not the case, Lemmy would be a ripe space for cybersquatting and “domain” hijacking. I could just go to a random server, or spin my own in just 30 minutes, create !PineapplePizza@MyOwnServer.tld and BAM! Now PineapplePizza is granted to me across the entire Fediverse. I become the ultimate master.
Sometimes the analogy to email is used. JohnMastodon@protonmail.com does not need to be the same user (and authority) as JohnMastodon@mailbox.org ; in fact, the entire system relies on the expectation that they “should” not be the same.
