For example, we have several adult and so-called 'non-adult' processing accounts currently at a few different processing companies, in both adult and non-adult but even after all these years of working online, im still not understanding how one product, site or service can be deemed 'high risk' when another one isnt, even if it is generating a sales lead the same way as a 'high risk' purchase.

Does anyone happen to know what criteria the processing companies, or Visa/Mastercard/Amex, etc use to decide if something is or isnt 'high risk' when it comes to online sales?
