Can I print Chuck Norris on a T-Shirt?

I’m starting up a new cafe press site because the last was shut down (for essentially the same problem, but that time they were right). The shirts have Chuck Norris vs various people on them, and today they blocked all of my images. If you want to see them, they are here: www.cafepress.com/chuckisbetter

My essential problem is that the name Chuck Norris is all over shirts on Cafepress, which clearly aren’t blocked. So why are mine?
