I thought of a great new tool that would help admins figure out who could be cheating.
How it works,
It would retrieve a users kill/death ratio via http://bfbcs.com/ and then display it in-game in a console in the top right corner.
Any user who would have an extremely high k/d ratio would be displayed in red.
Allowing an admin to get a sense of who is cheating... In the end it would be the admins decision on who get banned or kicked.
What it would look like,
