Yeah, it's almost like porn isn't the problem, it's crime and chargebacks.

All of those sites use high risk payment processors if they go through the major card networks.

I sincerely doubt that people are issuing chargebacks for Steam store purchases.

Our son kept on buying games using Steam and then getting refunds for them in order to buy another one instead

I told him to stop, because I was worried that too many refunds might result in Valve taking action against the account

Still, why bother with a chargeback when the vendor has a generous refund policy?
