@osma@darnell I believe the concern is the right to be forgotten hasn’t been tested in court for many if any federated platforms but people have used this rule to try and get their accounts deleted.
On mastodon deleting an account still keeps some identification for security and platform reasons and deletes when federated are extremely lossy - probably only about 85% effective and there is no assurance that remote post and account deletes guarantee a delete on the remote system when you can land on any type of fedi implementation.
I had two people try and claim GDPR right to be forgotten but ironically to protect myself I had to move their accounts to another system to track compliance of requests and cover my butt for any legal pursuers. They were running a fraud scheme.
