@MojangSupport Can you confirm to me that this address really is one of yours. "support@mojangdesk.com" I find the questions they asked really strange to ask from a support.

could you pls respond, there is a deadline, and if it's really you, I don't want to see my account blocked.

It just keep gettin' weirder, I received the same demand from yet another email. (support@mojang.contact)
