So here's the deal. Don't panic. Don't pay them thinking you will lose your domain or website if you don't. And don't pay them in the hopes you will receive higher visibility online. The simple fact is search engine optimization is all you need to gain traction, ranking and visibility. And that can be pretty affordable and sometimes involve really simple changes to your site.
There are a hundred domain listing cons (or shall we call them deceptions, lures, slightly false truths?) like this one. Preying on the unsuspecting non-technical website owners and the sad fact is, they make a lot of bank with these scams because people pay them and are none the wiser. Thankfully for my clients, they can just forward an email or scanned postal invoice and ask me if something is a scam or if they actually need to pay a bill. Since I manage their websites for them, it's typically a scam.
