I guess the point is that if we know an account is alt, but we don't know who it is. So does it make sense to allow an alt to participate?
I could say exactly the same thing for all other accounts who participated in pizza contest and all other forum competitions.
As far as I know airfinex didn't confirm that he is an altaccount, so it's all based on speculation that someone in forum is against royse, and I know plenty of people who don't like him.
All this topic and discussion at the moment is one big nothinburger, until I see something concrete aka evidence.
Note, I'm just not here saying I'm for or against it. Just creating lines of reasoning on the subject.
Now, if there is no clear evidence that the account is alt, then it's not really worth speculating.
