Will Working For Porn Website Ruin an IT Career?

An Anonymous Coward asks: "I used to work for one of those big web services firms, but it went bankrupt, and now i've been looking everywhere for a semi decent PHP programming job. I recently got an offer from a local porn site to do all of the programming for their site, including creating a whole automated publishing system for them in PHP. I also got an offer to manage the NT Servers at a medical office. Now, if I work for a porn site, will I ever be able to work for a traditional website again? Will this be a black mark on my resume? Has anyone here ever worked in the adult area of the internet? As mainstream, regular sites keep cutting staff, will more and more of us have to work for the seedier side of the internet?"
