How to report a scam?

[Revrent]

I just got an email from "Bleugold" telling me

Hey Mate,
Are you still looking?
Contact Jeff, he has one available for sale in at a fair price... Pm him jefftimothy223@garbagemail.DO NOT USE

This is an email scam that is similar to one on the Indian Forums that pop up from time to time telling someone who was in the WTB section to contact another person off-line to buy an item that they always seem to have. The interesting part is they almost always 'Just Joined" the forum or have only recently started posting. Once purchased/money gets transferred they disappear without ever shipping the parts. In the past I have played with them and gotten them to give a huge price reduction; give a military discount to a veteran from the Spanish/Canadian war (no such thing); match prices of made-up places on the web; etc. Today, I am just tired and wanted to warn others. I could not find a button to report it to admin.

Have a great day.
John
