I did a yahoo search for all sites with the link of the code:
link:
http://www.partypoker.com/?wm=2238044
http://search.yahoo.com/search?p=link%3Aht...moz2&fl=0&x=wrt
4 shady sites.
This affiliate needs to be investigated. He's also an affiliate of empire poker, so he's probably working the same thing there.
