I’ve worked in e-commerce since 2007 and I’ve seen every type of website/app selling all sorts of products and services. The issue the card companies have with content like this is that they have an incredibly high rate of charge backs. It’s the same with gambling sites as well. Usually a spouse one will discover the purchase, spouse two will claim they have no idea where the purchases came from, spouse two will say the card/account must have been compromised, then they call the card company to reverse the charges. I don’t agree with the process but it is the main reason I’ve seen merchant accounts rejected when my clients were applying for one.
