Hi,
Lurker refugee from reddit here.
Being a network engineer, I'm somewhat tech-savvy. But I'm having a hard time getting to grips with lemmy, or I should say the fediverse. I understand that it's a bunch of servers/instances that connect/federate with each other.
I also just learned or understood why I can't login with my user account from lemmy.world on lemm.ee. It's like email providers :)
But I've got a few questions that maybe someone who knows more about lemmy and the fediverse can answer.
- What happens to accounts, communities and posts when its instance decides it's been a fun few months and decides to shut down?
- Can someone register with my username on other instances, or is my username "taken" across the fediverse?
- If so, how are spoofing and/or scams using my username but on a different instance handled?
I'm starting to understand that it's not my data that is federated, but only links to the data in other instances. Would that be a good understanding on how the federation technically works?
All my account data is located on my "home" instance, but in turn my posts are stored on the instance where I posted or commented and linked to all other federated instances.
I could try my 2nd question myself, but I don't like creating more accounts than what I need.
Thanks!
I'm starting to realize that it's only the links that are decentralized and not, what I'd hoped for but was maybe obvious, my data/account.
I've asked over at [email protected] if anyone can register any nickname on any instance - essentially spoofing a user but on a different instance. Or if a username is "taken" across the fediverse.
Edit: anyone can register any ones username on a different instance. Spoofing/scamming isn't handled very good?
Edit2: post and comment data is federated too, so your posts won't dissappear, but might dis-converge(?) into multiple versions depending on things? :) This post helped me understand some of it: https://lemmy.world/comment/205763
