Flak, we aren't trying to disrespect, but please understand that we've been doing this for a LONG TIME, and believe it or not, we know what we're doing.
You mentioned somebody that plays in the server A LOT and gets spectated A LOT, and those of us with A LOT of admin experience that have probably caught more hackers than you have ever seen, don't see the tell tale signs in this guy, at least not yet.
We need proof. Use fraps or some other video recording software to show us what you think is so obvious. A good score is not what we consider proof.
You can check these forums (or the internets) for what hacks look like.
