All of these are targeted at businesses. The first would be the fear of losing your website, which really would be a massive pain in the butt. Sometimes companies will send you "renewals" telling you that your site registration is expiring. They want you to re-register with them instead of your current registrar, since a lot of people don't even know who their registrar is.
Now go look that information up and keep it handy so you won't be fooled into switching.
Another scam that comes up every once in a while is something like this, that's designed to make you think that someone else is going to take your website:
Dear President & CEO,
This is a Network Service Company which is the domain name registration center in HongKong,China.
On June.13, 2011, we received an application from Meihua Holdings Group requested"acaketoremember" as their internet trademark keyword and China (.CN ) domain names. But after checking ,we find this name is conflict with your company's name or trademark. In order to deal with this issue better, it's necessary to send this email to you and confirm with your company whether this company is your distributor or business partner in China?
If you did not authorize, please let us know within 7 workdays, so that we will handle this issue better.
Looking forward to your reply
Now the point of this is that when you panic, thinking that someone is going to be using your website, they offer to sell you the rights to use the new site, usually at a highly inflated price.
If you really care about someone using your website with a different extension at the end, just go to a registrar that you know is legitimate, like godaddy.com or yahoo.com., and register it yourself. You can register as many domain names as you want, so have at it.
Don't be fooled into thinking that you need to protect your business name in China, either, unless you're planning on expanding over there any time soon. Chances are it won't matter.
