Why doesn't Yahoo Spades get rid of people who purposely jammed the game room?

For more than 5 months someone has created a program that jams yahoo spades (it might happen in other yahoo games as well).

When you send an e-mail to Yahoo abuse administration, you just get a form letter e-mail reply back. It is obvious that no one is reading it. Since some players pay to play these games and tournaments, why doesn't Yahoo Customer Support get to the root of the problem and find out who is jamming their gaming website?

No wonder their stocks are declining - I think it is a disgruntle former employee - because it would seem like no normal person would have that much time to keep writing programs. Just arrest the clown!
