As I understand it, domain registrants are required to provide accurate contact information. Since that's obviously not the case, if you contact the registrar, they should attempt to obtain accurate information. If/when that fails, they may turn off the domain. I, of course, have never tried this before, that's just want I've gleaned from other people.
John, it was domain.info instead of domain.com. The content was not the same (I didn't have any content on my site at the time), the .info had one of those placeholder pages up with some search and directory.
Flash and Chad, thanks, I'll check out contacting the registrar of the .info. :)

That's why I suggested that you report it to the registrar where the domain in question was registered.
