One of our clients just received and responded to a letter from Domain Registry of America that said “your domain is about to expire, send money.”
If you get a letter like this, tear it up. Domain Registry of America and a few other firms try to get you to switch your domain name to them so that they can charge you a lot more than you’re paying right now.
Luckily, the organization that manages the universe of domain names, ICANN, set up a rule that, to switch domains from company A to company B, you have to get an authorization code from company A. Our client was asked for this code, asked us to find it, and we said, “Whoa! Are you sure this is what you want to do?” stopping the scam in its tracks.
Another form of protection is to “lock” your domain name. Unless you or your administrator/webmaster unlock the domain name, it ain’t going nowhere.
Here’s more information on the practice, which is called “domain slamming”: http://en.wikipedia.org/wiki/Domain_name_scams
