There is a forum thread that is discussing "duplicate suppression" with Income Access. In the context of the discussion, Louis has indicated that a "single brand" uses that technology in their anti-fraud campaign, which resulted in the inability to credit the player to the affiliate in a proper manner (said another way, IA is claiming this is the brand's fault, not theirs).
In the context of the discussion, the brand in question is Coral. I would personally be appreciative if you would participate in the conversation. The post where Louis placed the blame on the program is here. My hope is that your participation will clarify and work out the bugs in the anti-fraud process so that you as a brand are protected and that affiliates are fairly, accurately, and properly credited with the traffic we send your way.
Thanks in advance for your participation, honesty, and cooperation.
