It's a tough situation.
MaxBounty (despite what some people have said here) *is* actually a credible network, otherwise people wouldn't use them in the first place, and we wouldn't see a wide array of affiliates saying good things about them.
At the same time, regardless of the TOS, I really think there is actually a case to be made when dealing with a $6,000 payout being withheld when the advertiser says they are happy with the traffic. MaxBounty *does* bend the rules of their own TOS when a discussion is had between the affiliate, the AM and the advertiser regarding the traffic, as most networks do. So there is one mistake on the part of jason666 right there -- jason, why didn't you discuss your tactics with your AM and the advertiser before you sent the traffic, or at least after you got a payout to make sure everything was ok before moving forward? Maybe you were scared you'd get banned, but the truth is that most AM's (even the ones at MaxBounty) are more likely to appreciate your concern than look down on you for it. Communication is key, just like any other relationship in your life, so that is something you maybe glossed over at your own expense. But I really do feel that MaxBounty is screwing you here. It's very unnerving to see.
So, can you provide some sort of proof that MB was paid by the advertiser? I don't ask for my sake, or the sake of the BHW community so much as for your own. Cuz if you can prove that, you might actually be able to take them to court. It certainly would be worth the consultation with a lawyer.
