Progressive Degenerates (Political Commissars / Blacklisters)
These fraudsters masquerade as payment processors, yet operate as political commissars, colluding with a horde of judeo-athiest mystics to blacklist anyone they deem, by their inverted metrics, a heretic. And if you're not actively aiding and abetting the gang raping of Christendom unto her death, then you're a heretic.
