Yeah, this is disturbing. He's admitting he used social engineering to get back into his own locked account and he's happy that it worked. Assuming he did this over email / web the "proof" he sent them was probably a photo of driver's license which really doesn't prove ownership of identity when your account was just hacked.
We really need a third party service that allows you to walk up, have some DNA taken, verify you are who you say you are, and then unlock accounts in these cases. We can have the government do it, they have all our DNA anyway!
