Asher is sort of right. If there was some impossibly cool domain name that existed that I could buy - like, gee, I don't know - google.com; I wouldn't announce it to the world in case some guy bought it up from me. Unless you happen to own a trademark or something that guy will have all the rights to the domain name. It's always "first to the punch". Common sense really, I don't think that's going to happen here.

As for "domain security", what?
