courteneyfish: Report the player to WGT via the Contct link at the bottom of this page. Hopefully they'll be removed.
This particular cheat has been around a very long time, only choice is to wait it out.
I will usually open another browser in a smaller screen and check out various news sites, catch up on current events forums etc. You need to keep an eye on the person, they will eventually load. You used to be looking at about an hour till you win, then I recall WGT changed something and it was like a 5 minute load timer. They disconnect after 5 minutes of no load.
So either WGT removed it, or the OP failed to wait long enough.
