Add a way to show your win streak and then if you loose a win streak to a hacker you would be more likely to report them. However if your win streak was below a certain benchmark (eg. 50) the hacker would still be banned however if your win streak if higher if you record a hacker killing you you could regain your win streak. There should also be a leader board for win streaks and maybe the top few people on the leader board may have to be spectated or something if a hacker tries to get onto the leader board.
