Either Sigma is someone's alt, to which if you are, hello again.
But in the more likely chance he's not, his ID is in the 30,000s and registered in 2011.
My ID is in the 1000s and I registered in 2007. I am almost 4 years his senior (in terms of Blockland years).
But, then again, ID racism is an old staple of Blockland that I try not to bring myself down to. It's obvious that this guy is just being a jackoff, which is fine I guess. I mean no one is going to respect you for acting like that, but it's his account, he can act on it anyway he wishes.
