I think adding to T&C that search engine spam will forfait any revenue is the way for affiliate programs.
A lot of poker rooms are promoted now by a lot of people that don’t have websites. I can say offline promotion using bonus codes is around 10% of total affiliate marketing. That simply mean that no more people promoting offline will be approved.
Also each of the bad guys can setup a nice looking site to get his affiliate link and then use his tracking for other purposes. Most people here have 5+ sites. I doubt anyone ever submited them all when aplyed for a program.
