Not only can you not get billing, I don't think scat is considered legal in the US, I think it's been successfully prosecuted as obscene.

I remember reading about a straight program that got busted not long ago called "browndollars.com" (great name) that had among their finer properties "brazilianshit.com." If I remember correctly, the US-based owners were trying to claim they were in Brazil, but got busted, and some other company acquired the site from them, but I believe it cannot legally be marketed in the US.

There are probably a couple of shady billers that would take it. Segpay seems to accept almost anything, so maybe they will bill for scat.
