I experienced this once. Someone contacted me about a domain I had no use for with a pretty good story about why they needed it. He even showed me his work as a small timer in the entertainment industry with an interesting sounding project he had in mind for it. He offered a small sum and I decided to just avoid the hassle and give it for free as I probably would of let it expire in a year. I even paid the small fee yahoo wanted to transfer it.
I was curious and went to the site a few months later. The fucker is a domain shark on the side and the sites a parked page with a forsale contact on it.
Moral of the story is to google their name and spend a few minutes before giving/selling domains.
I had registered getwellconnected.com, which I had vague plans to use for a nonprofit idea to let sick kids in hospitals connect together.
I got an email from someone claiming to be a consultant working for a small hospital. They were building a site and wanted to use that domain name. They offered a fair but relatively small price, and since I didn't have immediate plans to work on my idea, I agreed to sell at the offered price - no higher.
A year later today, I see that the domain is parked. It's quite a good and general domain name. I registered it with plans to use it. What a ploy.
