I’m so confused, I don’t even know where to ask this stuff. Here are my questions, hopefully it helps others in the future:
- I see a bunch of different “Lemmy’s” here. What are these called? “Flavors” of lemmy? Lemmy “websites”? Lemmy “instances”?
note: I’ll call their collective entirety as “Lemmies”, for the remainder of the post
-
If I created an account here on lemmy.ml, (
obamacares), does that account also exist on other “Lemmies”? -
Do posts and comments on this Lemmy also exist on other Lemmies?
-
If one happens to be banned from a specific Lemmy instance: does one also get banned from other Lemmies?
-
In case the answers to the past 3 questions was “No”: then what is the relationship between the different “Lemmies”?
-
How are those Lemmy websites stored and served? Is it just a machine the person who created the website maintains — or is there more to it? (some kind of decentralized collaborative server pool, or some blockchain stuff, idk)
-
How much “privacy” can I expect inside these Lemmies? For instance, if I talk to some user through dm’s, can anyone else see our messages?
-
If I delete a post or comment: is it gone for good — or will it linger for the eternity in some internet server somewhere?
I probably have more questions, but I forgot now.

Correction what are these called? Though they are called instances now, I truly enjoy saying the word “lemmies.” That is what I will be calling them now.
works less well with different instance names but go ahead lol
Instances is fine but I always thought calling them servers was the most pragmatic choice. Many people already understand the general concept of servers so it seems to be less confusing/overwhelming to newcomers. Lemmies is fun though, and it’s really just an abbreviation for “Lemmy instance”, so I feel like it’s not even wrong.
