on the other hand, i've seem cases where people who were banned simply because they were too good and people started reporting. And one special case when one guy was banned because he pwned one of the developers.
the issue with tark is that there is zero anti-cheat. death matters in tark when you can lose days of work having the level of cheaters that are currently in tark is unacceptable.
Showing the players the numbers is pointless when they cannot realistically eradicate the cheaters anyway. Cheaters (and other forms of crackers) are always one step ahead, sadly.
