Is GoDaddy stealing my domain name suggestions?

Whenever I go to search for possible domain names on GoDaddy and find one that I really want, I'll usually wait a few days before making purchase just to ensure that's the one I want. But on more than one occasion I've gone back and that domain will be gone. And, I'm thinking it's highly suspicious those very unique domain names could be gone. Just wondering if Godaddy is somehow taking the domain names being searched and offering them as alternative domain names to people on their site. If so, I will stop using their suggestion tool.
