If you don't know what I'm talking about that's good, don't worry about it. No harm will come to you by not knowing, I promise.
If you've read my bug report from today, and its something you use for the free kills then I apologize but it 'is' a bug and had to be done. If it makes you feel happier, the only way that I can think of for fixing that easy exp / cash bug would also fix the aimbot-ness of bots period. The reason for this is that bots have a distance check rather than a line of sight check, which allows them to see and kill you through walls and other barriers at a close range, but at a long range makes them sitting ducks.
