No different than denying credit card processing for firearms or ammunition. Next, political contributions to conservative groups and candidates. That should get his attention.
I've heard from someone who knows:
Pornhub is the new haven for firearm-related victims of cancel culture. They can put up their gun videos there without fear of backlash. Particularly stuff related to 3D printing.
Maybe that's what this Mastercard stuff is about.
They’ve also denied the use of their cards to conservative YouTube vloggers. The vise is tightening.
Forget credit card processing, I can't buy ammo mail-order because every damn' site thinks all of Illinois is Shitcago! Almost none of the online ammo sites ship to Illinois because of Shitcago.
