I worked for a site in the adult space and fighting credit card fraud was a huge problem. A lot of effort was put in to preemptively trying to catch fraud (e.g., when your credit card country doesn't match the IP address and/or the location of the profile you're creating) and refund the charges before it even got to the chargeback stage. Inevitably there would be fraudulent chargebacks against the site when someones partner would read the credit card statement at the end of the month ("No honey, why would I use that site? Our credit card has been hacked!"). There was a team of people who would prepare reports of usage to fax to the banks to challenge the chargebacks. You want someone at a bank to get a faxed copy of naked pics? Upload them to the site and then deny the charges. Easy!
