I'm not one to normally point to MS as a good example on much if anything but I absolutely love the way they handle Xbox Live cheaters/griefers/other rule breakers that come onto their forums and claim innocence. I've seen many, MANY people go to their forums to proclaim their innocence only to be met with EXACTLY what they did splayed out for everyone to see. I've even seen their team post what steps they did to verify their information including in-depth investigation details.
