There are definitely a lot of links in this chain. Maybe leafo can chime-in and say exactly what happened with Itch.io. But I suspect that someone downstream of Visa/Mastercard anticipated that the payment card companies would not permit the transactions and relayed that back up to the merchants, and they shut it off preemptively.

But it's hard to say. Mastercard is now saying that they never said or did anything. So where did the outrage come from? Someone must have done something.

It sure is tragic that benevolent and majestic Mastercard is having their name thrown into the mud over this. Coincidentally, it sure is convenient that they have a number of middleman scapegoats who can take the blame on their behalf.

All Mastercard has to do is say “We ordered payment processors to let Valve sell their games”. It is sure convenient that they stop at “We didn’t say the opposite.”

FWIW Mastercard are simply lying, as anyone who has ever had to touch adult payment processing will tell you.

There's even a (non-public) list of keyword banned terms.

Indeed, and the keywords are vague and they refuse to rigorously define them. Adult payment processors just run around in the dark until they trip over one of these landmines.

Even the (rare) categories of content that have been legally determined to be non-obscene (e.g., werewolf erotica [1]) can fall under banned keywords (in this case, “bestiality”).

It’s a stupid extralegal system and ought to be destroyed.

Throughout this our only contacts have been representatives at Stripe and PayPal. They indicated that they got a notice and kicked off their own audit.

As far as I'm aware, the Collective Shout letter caused a "formal card network inquiry" to originate from both Mastercard and Visa. I did not have access to the actual inquiry, but my assumption is that it wasn't "we see this content, take it down" and more like "we saw this letter, look into whats going on before we do our own investigation and fine you"
