Fortune and Income Access are both great, and there isn’t much difference between how they compensate and how 888 compensates. If you are looking at CPA most everyone here would advise against it, though at last look, Fortune had the best CPA deal.
As for 888, they locked our account for supposed bad traffic (bonus abuse or chargebacks). You can take a look at our site, but there is no way that a claim of bad traffic can be supported. More likely, we had very little traffic for them and the one person that signed up was a chargeback or something, so they got tired of forwarding the negative amount each month. Oh yeah, they have negative carry-over, another reason not to use them.
