They market via direct mail, and send what appears to be an invoice for domain renewals, often complete with a message indicating the client's website is going to be taken offline if they don't act fast. They're presented in a fashion that highlights the "scare tactics", but if you read the fine print, it shows that it's not actually an invoice.
These companies make their money from the people who don't know any better and end up sending a check for domain registration services, at a rate of typically 10x the normal rate you can register a domain with a reputable company like GoDaddy.com. If you receive one of these fake invoices, our advice is to throw it in the trash where it belongs. After all, if a company has to trick you into doing business with them, does it really matter what they're trying to sell you? Avoid these companies unless you want to spend unnecessary money and cause yourself a headache.
