Yikes wow! I still see all your history, I think you're good. To go full Agatha Christie, from NIP 62:

-Clients SHOULD send this event to the target relays only.

-Relays MAY store the signed request to vanish for bookkeeping.

... from the above Plebstr could have theoretically sent a signed right-to-vanish event BUT luckily the "target relays" was only one of your relays, and that relay deleted everything including the request to-vanish event itself, but Primal, seeing as it pulls in everything, somehow had time to log it internally and then locked you out.
