If an account is created on any specific server, like !Lemmy.world does that mean if the server does shut down, the account data is lost?
Also for username availability, could we create an account in a different server where the name is not used yet?
Agreed. Lemmy needs “multireddits.” Currently it’s design is both a blessing and a curse - if one community goes toxic, it’s easy to find and join a rival community in another instance - that’s the blessing. But the segregation between similar communities is also the curse that you’ve described. Plus, if a popular instance goes dark, there goes that community. Multis would help alleviate both issues.
I didn’t realize that if a server goes dark so does it’s data. We will need archival tools for this. If the content can’t be counted on, the platform will not become viable.
