Big porn companies are very serious about PCI compliance. They also closely monitor their fraud numbers. If a MID (merchant ID) goes above 5% (volume or cash amount) fraud, the processor could get fined by Visa/MasterCard/etc ($50k+) and lose the right to accept credit card payments for that particular payment network. Processors who handle porn (high-risk) accounts will often have a general, shared account they'll let you use, because they can take measures to average down and hide the fraud. However, they charge you a premium to use that general account, so you're better off using your own if you have other measures to control fraud.
My former company solved this problem by simply acquiring a payment processor company. They had total control over their processing that way. As a bonus, they had access to other porn vendors' account activities, since it was one of the 4-5 major high-risk processors used by porn companies. It was a win-win for them.
re acquisition of their and competition's processor
They just keep getting more clever, devious, and entertaining, don't they? Shit, I'd do my own Braintree for my porn company with the company's positive gains from legit customers covering the losses from the others. Who cares if my bottom line at my main company was good. Success of processor could even pay for better fraud management.
Of course, already having enough cash to buy an established one is always nice. :)
