If you play 500 games and run into 5 or 6 cheaters, how far off do you think your numbers will be? It's not going to skew your rating so much that you can't accurately judge your improvement.
Do I hate cheaters? Bet your ass I do. But they are part of internet chess. To freak out over it isn't going to solve anything. I believe this sites staff do all they can to eliminate cheaters. It's not possible to find them all. So we all at some point will face a cheater or three. We can let that affect us and worry and fret over it, or we can accept it as the reality of internet chess and soldier on....
I don't see any way members can do more than report it to the staff if we believe someone was cheating. Then move on to the next opponent who hopefully isn't.
I am in no way advocating cheating. But I AM advocating not letting it bother us so much we lose perspective. Over time rating numbers will level out and any points lost to cheaters isn't going to mean much. And I still say "valuable points" is overstating the value of these ratings numbers. If you're 1560 instead of 1575 does it make you a worse player?
I wish they would eliminate the public rating system in V3 and go to a private one.

if cheater dont arrive 2000+ that might show us how good and fast this server is by finding and disable them.
Where does that leave the honest player who might spend 20 years of his life to get to 2000 but, he is constantly pushed back somewhere between 1500-2000 constantly, because of it ?
