It seems pretty damn loose, but of course, it's hard to test since the outcome ruins your PayPal account. I found this: https://m.imgur.com/a/RnpRm

that's what the SDN list really is, just some common names of people, organizations and countries.

it's up to you to figure out how to turn that into not selling to the wrong people and going to prison.

True, but that doesn't seem like a good excuse for a dumb grep-ish solution on all fields.

Some smart terrorist is going to legally to change their name to "Thank You" and screw PayPal :)
