Darn those desperate banks

It really creeps me out how many "checks" written with my name on them that are sent to me in the mail by credit cards with which I do not necessarily have an account. I'm not normally very easily spooked when it come to identity theft, but this just seems like a BAD IDEA. I've been getting them regularly for years, so I assume they haven't become a liability due to fraud or theft. Maybe I should use one to buy a paper shredder.
