I found out about a bunch of scammers targeting website owners from Writer Beware. Essentially, a group of scam artists are looking up who owns a given website and then sending the owner an email from “the US Copyright Registry,” claiming that the website in question is not copyrighted. For a measly $350, the scammers will take care of it, though.
Unfortunately, if you run a website — and if you’re a freelance writer, I’ve been telling you to for the last who knows how long — you open yourself up a bit to these sorts of idiots. The best protection you can have against them is to know your own legal rights, like the fact that you hold the copyright on your website whether or not you’ve registered it.
