scroll to the bottom of Brazzers, there are 4 company addresses there, so they have at least 4 different merchant banks for Brazzers.com, under 4 different companies (4 different jurisdictions). they also list 4 different IPSP's so they have 8 different billing options.
loosing 1 does not change anything for them, but would heighten risk, they would say they use 4 different merchant banks in order to optimize throughput and minimize international interchange fees, but realistically, they are curbing their chargeback risk, so they now only have 3 places to spread their risk among.
if a couple more banks chose to not do business with them things would get dicier, as they do large volume, and it would be pretty risky to have all their transactions in 1 account, legally it presents similar liability, but it is right there for the card associations to see when it is all on one account. if that happened I would think they would start pushing volume to the ipsp's to minimize risk.
that's when it would start to affect them, going from paying 4% to 10% fees, and being bound by the rules that are imposed by IPSP's. On top of that, they would go from getting daily settlements at the bank, at the end of each day, to getting daily settlements from an IPSP at least 7 days held back (loos a weeks cash flow, which for them is likely millions).
yes, I am sure other banks would be willing to work with them, but it is not an overnight open an account thing, it takes a lot of work to get a merch account quickly, and sites the size of brazzers take a while just to pass G2 scans for compliance.
If a bank said they were closing fabians accounts for chargebacks, I would say it is no worry for him, when a bank refuses to work with someone because of potential reputational damages, there is a good chance others will follow suit, and it is potentially catastrophic for them.
