Heh, thanks for sticking up for me guys. I've chucked the book at these sellers.
Unfortunately, eBay likes to take several days to take action, and by then the auction is sometimes over.
Interestingly, this latest thief bought the stencils from the thief mentioned earlier in this thread. And then immediately went and resold them himself.
Kinda sad to see people profiting from my work without giving me credit. What's sadder is that the bidders buying these stolen goods don't realize they can get even MORE stencils on this site, often for less than the auction is asking for.
