I dont give incentive to players because that violate terms and conditions.
PartyPartners start partybets on december and im one of 1st’s afilliates starting promoting the site, so i place a bonus code on severall foruns (with permission from owners) after a google search i found some webmasters starting using that bonus code 
(lucky me) thinking was an official code for partybets (they maybe dont know what is a tracking code). They use the tracking url but advertise my code and the code overide the tracking url.
