In the first case I don't have nothing to say but in the case of this user v1rtu0so I can tell that is a real user even an old one, despite the case his account is pretty new, he is an user that is very involved with cryptos currency, you can find him on places poloniex and just-dice.

 I know that is him because i was chatting with him about this thread and he told me about his choice, but don't take my word, he is able to provide proofs that he owns that account if it's asked.
