Intentional betraying is clear cut and they can write a program to identify it. If you are in a firefight with the opponent and a guy walks into the line of fire, thats incidental and no biggie. You are sitting there and some douche pops you for no reason, they should ban the **** for 24 hrs, that would stop that sort of stuff. If they do it intentionally again, 48 hrs. Every time they betray a teammate intentionally, they add one more 24 hr period. That would stop intentional betraying real fast.
