What is a trademark infringement verification with domain names?

[chika]

Some one sent me this question about buying a domain name off me, i think its a scam..

"I've found not all the appraisals are accurate and provide the trademark infringement verification. So I accept real manual appraisals from trusted sources only. "

Verifying that the domain name is not infringing on any trademarks. I registered a domain name with the words "playboy bunnies" in the domain name and a month afterwards I received a letter from Playboy notifying me that I was infringing on their trademark.

As far as verification, you just go to the Trademark database and check on there to see if the phrases or words used in the domain name are trademarked already. It's free.
