Gaston, you should try and get in touch with guitar companies like Fender and such, they got down 80 % of websites proposing fake Gibsons, Fenders etc ... It actually worked, they got all the major websites down and the women who own the biggest one is now in jail ( i ll have to find the name i can not remember it) then I know tattooists don't have the same legal force but still, it could be worth checking
