There are 2 main ways that companies try to scam you in regards to your domain. One tricks you into thinking one thing when you’re really doing another; and the other way tries a mild “scare tactic.”

A company sends you an email telling you that your domain will soon expire. They request payment within a couple of days or you will lose your domain name.

They send you a form that they want you to sign.

You think it is to renew your domain name and it really is like a permission slip.

You will be giving them permission to take your domain name off of your hands.

You will give them control and not even know it.

A company contacts you and says that a new domain is ready to for registration. The new domain will look just like the one you own, but it will have a different extension attached.

For people who want to protect their copyright or name, they may want to snatch this domain, but it may not be really available, causing you to pay for nothing.

Thanks for the heads up. Would you care to share any of the companies involved?

I have heard about these scam which is why I always insist on talking to customer support guys before getting on to an email.
