Its always funny to see some program owner complaint like this because some affiliates do a better job than them with SE/Adwords ;) lol
You are the 2 program owner talking like this over a 3 weeks period. I hate this new trend really. If ppl send the sale , THEY NEED TO BE CREDITED for the sale.
Period. Even if they take over your top ranks, use adwords or any legit way to generate traffic.
By any chance, if any other program owner think like TheDoc and i dont know about it, please post, it will be a pleasure to remove your program as well from my traffic system.
