No, I did a great deal of research before choosing a domain name that didn't conflict with their trademark. "my" "pimp" and "codes" are all general terms and there's no way anyone could get a trademark on those, unless they got one on "my pimp codes" but as of now there isn't; so my name was registered first, and I have right to it even without a trademark. As for a "theme"? theres no way a company could control the theme of your website. That's just insane. They can't control the content of my site (unless you're using copyrighted material) and the can't get a copyright on a few lines of universal css/html. so unless your actual domain blatantly contains their trademark, you should be ok. And anyways, I asked "Tom" and he said they don't mind the code sites at all, since they only promote/add benefits to myspace, so unless it's conflicting with their business and name they won't come after your site; they'd just be shooting themselves in the foot,
hope that helps
