Well, for one, if you were a bit patient you'd find out that they DO update but it takes a while. It's something to be expected that not everything will be up and running on an online game when it first releases.
However, I do feel your pain.

I've been patient. I've had the game since day one. One time it went like 4 days without updating. I went from like 198 wins to like 270 in a matter of seconds. I'd rather just use that site to show how good I am than that ridiculous rank system. People logging on two ps2s and just beating themself over and over to get a good winning streak, it's ridiculous.

Rank doesnt mean shit man... You shouldnt worry about it. I know guys with shit records and they are 10x better then most of the people that play.
I played a couple of guys with one of those sick 500 wins 5 loss records and fucking wrecked them with shit they never seen in there life. Then they bitch and leave real quick. Nothing but rank whores. They only stick around when they are winning.

That's what I'm saying... the rank on the gamespy system doesn't work. You actually have to be good to be high rank on this ladder.
