Chill, no one is going to register an account the first day they see the forum not even I did.
That doesn't mean anything.
He actually joined blockland around 3 years ago. (Looking at the ID)
I believe 40k ID's were sold around 2012-2013. Judging by how it's a high 40k I can say it's from 2013 at least. If this is correct this means that the user has owned Blockland for about 1.5 - 2 years maybe depending the on the month he got it.
Either way the person just probably found out about the forums very late or just decided it was a good time to start posting now (like me). Besides he hasn't actually done anything at all except upload a graffiti print which is actually pretty sweet and posted it in the wrong section. He made a new thread in the right section, but locked the thread before anyone can post for some reason? That's the only weird thing about the guy up to this point.
