A little advice.
If you or anyone you know opened a message like the one you posted you had better do a full system scan.
Riding on the backs of a lot of those 'scam messages' are trojans or other harmful scat. They will steal your passwords, credit card info etc.
I was selling a very valuable vintage rock concert poster on ebay. Had lots of bids, responses and questions from collectors, some from Europe, then...
I recieved a message via MY MESSAGES on Ebay, before thinking or scanning the contents I opened it, Crap, got me. The message was from a registered user in Africa, addy looked ligit, all seemed right, they even had a good deal of feedback. I turned it over to ebay fraud and they took care of it. I now isolate and scan all messages/email before opening them.
