Who defines this?

Congress has passed a bill, which the President is expected to sign, that makes it illegal for porn sites to use domain names that are misleading. Who’s going to decide what’s misleading? If I were to start selling naked pictures of myself on this site (don’t panic, I don’t plan to), would kalsey.com be a misleading domain? It doesn’t indicate that there’s porn available. It’s just my name.

The authors of the bill claim that they are only trying to prevent false advertising, but there’s no parallel for that in the offline world. In Sacramento there’s a store called Goldie’s Books. From what I’ve seen of the front of the store, I don’t think they sell books.
