No, Bonustreak not all sites that offer player gifts are attempting to do CPA scams, but you have to admit there are MANY that do. Unfortunately that does create a somewhat negative perception of gifting for affiliates that are honest.
Its just like CPA deals, the vast MAJORITY of affiliates that operate under the CPA model are honest.
The few BAD “affiliates” that try to abuse CPA programs make it difficult on the honest affiliates and casinos who try to work CPA.
