Why Isn't There A Screenshot For This Ban?

From PunksBusted

The idea of PunkBuster and any similar anti-cheat system is not to let you carry on playing long enough that PB has enough time to take and upload a screenshot back to the server.

If it can be done, then the cheater should be kicked and banned from the server before they've had the chance to ruin everybody else's game. The idea isn't to keep them in a server until they've had chance to win a few rounds and then boot them.

Screenshots are a nice visual indication of a cheat, but a violation is better than a screenshot for the people that actually had to play with the cheater.
