If you were willing to upload your driver's license and passport for a mere chance at getting back an account you don't give a crap about I'd hate to see what you'd do for one you do care about! Facebook demanded my driver's license at one point out of the blue. I simply abandoned the account, I was already pretty over them at that point anyway. About a year later it let me log in just fine and had forgotten all about how badly it had needed a scan of my license for security. In fact I didn't even remember the password, it just auto logged in from an email link.

You kind of confirm what I suspected though, that they'll just keep asking for more stuff leaving you more exposed and they're under no obligation to actually give you the account back no matter what you do.

I don't use discord but IIRC I read that if your account was banned they were asking for a mobile number to get it back. Instead of getting it back if you complied they just added the mobile number to their ban list so you couldn't make a new account with it.
