Simply - We don't ! We hide the new players.
I propose a system such as in Town Of Salem.
Players will recieve pre made names
That way when we are in a game, No one will know who is a new player and who is a veteran player.
Anon setups are not as played as the normal open setups, and this has to change.
Another good idea is to make a round only made from Anon setups.
P.S.
Rutab: "Everyone being anonymous would take away the fun of playing with friends"
Well my friend, Playing with friends is pretty much cheating. If you want to play with friends, play unranked games!
Rutab : "Cheating would be so much harder to find if games were anonymous"
mmm no . . . Names will be revealed after the game. Its actually more easy to spot 2 cheaters, if in 2 different games where no one knows each other - they know each other.
And Mods finnaly will read the games, when giving violations.
