Cafepress won't print random hex numbers

It looks like printing random hex numbers is too much for Cafepress. After this week's digg fiasco, I created an image to put on t-shirts, and they've now taken it down. Come on, it's just a number!

I suppose it could just have been an overzealous staff member, too eager to hit the censor button, so I've now created a larger image, and purchased a t-shirt, to see if I can get my hands on one before they get jumpy again.
