Okay.
What does it mean that e-mail, username and passwords must be complete and true?
Burner e-mails are not allowed on Lemmy.World. Any content in conflict with the Terms of Service is also not allowed, usernames also being content. Passwords must be complete and true in the sense they should meet the security requirements of Lemmy(World) during sign-up, and this standard be maintained during any other later change.
What are your demands for content federated to you?
We have not a Federation Policy in place, as does no one. Any content visible on Lemmy.World(which also includes federated content) would be moderated in accordance to the Fair Use Policy of Lemmy.World.
How does the 18+ rule relate to users on instances with lower or no age requirements?
This rule, as well as simply serving to fulfill legal obligations, is also an extension of a statement from our Privacy Policy, which states in case we realize an user is underage, we will delete all data associated with them, including their account. Since the Lemmy software does not run a feature to check or confirm user age, this policy is only to be enforced upon moments of being made aware. As with our local users, upon the moment of realization, a federated underage user would also be restricted from interacting with our instance, and any data associated with them deleted.
How does it work if a user wants to delte their account and all relevant data as per GDPR or similar if it’s federated?
When requested appropriately and confirmed by us for security purposes, we will(and do) gladly delete all of an individual's data that we have. We are not responsible of what content is in other websites.
It is checked automatically and enforced automatically upon detection, for every single user. It is not unenforcable at all.
Like there isn't already? And it's got nothing to do with anyone's rules or documentation.
