Good afternoon!

I have got a question: one of my friends plays the BuzzerBeater. He has got a brother: the brother liked the Buzzer, and they decided to register. But is it OK to play 2 users per computer? They will never make a bid the players of each other, and they never will play scrimmage with each other.
So is it possible to play this 2 users?
1st team: Kalászi Krampuszok
2nd team: no registered yet, because he is afraid of ban.
Thank you for the answers and have a nice day!
