I think step one is to get the internet autists digging to find out who and what these payment processors are. There are people operating these levers of power but they are currently a complete unknown. Once they become known we can move on to formulating some method of applying pressure to discourage them from engaging in bad behavior but right now they're mysterious nebulous forces as alien to us as the weather in ancient times. They just sort of act on their own with no rhyme or reason or capacity to be influenced.

TL;DR: Information gathering to figure out whose house needs to get TPed.
