The {dFb} UT3 stats page  was coded by {dFb}eMac and was publicly announced in the official UT3 forums. eMac is the man to talk to for things like that, I do alot of the website stuff. You won't get any flak from gamespy or any other for that matter unless there dickholes. Generally when someone releases something like you have it's pretty well appreciated. As for the cheating there are a few people working on some stuff but it's not being discussed publicly. But keep an eye out, something should pop up soon.
