Steve2golf: Me thinks multi accounters are big money here, I seen a stat that wgt only receives 16000 unique IP hits per month, so if you are looking to kill them 1 account per IP address is the way to do it.
I think people playing from their work are big money here. Why else hold on to the no-client-installation required ? 2 colleagues from the same company-location play with the same ip address.... 1 ip address 1 player would cancel out a whole lot of people who might be cheating their boss, but for sure are not cheating in the way we mean here.
...now, back to work....
