Nothing that can really be done about it, WGT doesn't want to piss off their potential cash customers so they aren't going to do anything significant about it. I play a lot of BLITZ now and the disconnects are much less and if I play stroke play I try to limit it to my friends.
One comment, based upon my year on WGT, the quitting isn't limited to any country, I have seen it from everyone.
