Solid advice from @llllllllllllllllllll on the email trick.
Just one other major thing I’d add since we’re on the redact forum: if by “nuke” you meant you wanted to wipe your message history too, the bad news is that official account deletion doesn’t actually do that.
It just renames your profile to Deleted User #0000 and anonymizes the data, but all your actual messages, images, and hot takes stay up in those servers forever unless the server admins manually delete them.
Since you’re suspended, you can’t use a tool like Redact to scrub your history first, which is the real “gotcha” of getting banned. You’re basically locked out of your own cleanup process.
Also, regarding the phone number: even after the 30-day hard delete, the number sometimes enters a “cooldown” period where it says it’s still invalid for a few weeks. If you need a new account now and the + email trick works, you might still be stuck on the phone verification part unless you have a spare prepaid SIM. (Don’t bother trying Google Voice/VOIP numbers; Discord blocks almost all of them now).
