Some of them are probably even doing it right now.

Stuart Lawley caught on to that trend and started ICM Registry, a service that lets you register a website that ends in .xxx. It also maintains Search.xxx, a Google-like search engine for finding  exactly what you want in your adult entertainment.

We spoke to Lawley over the phone today about how the registry and its search engine works.

One key differentiator: Porn is very popular among hackers as a lure for unsuspecting searchers. Who's going to admit that they visited a porn site and got their credit card stolen? So Lawley decided to address those concerns head-on.

"A site with a .xxx domain offers the same dirty porn, but the idea is that it's there in a clean wrapper," he said.
