Can I make a suggestion, Shawn(and everybody else)?
Don't mess around with these people. Delete it and move on. While scamorama is funny(it was mentioned in the New York Times last week, as a matter of fact) it fails to mention that these guys can actually be DANGEROUS. There have been about two dozen murders over this kind of thing...people get lured to Nigeria and then held hostage(a few hundred) or murdered( a couple dozen). For real.
And the Nigerian Government(a division of Shell Oil Co!) could not give a whip.
Okay, so maybe you are not daft enough to go to Nigeria over this, BUT...
The point still remains that these people are NOT as stupid as you think, and the more you communicate with them, the more you open yourself up, they can do all sorts of things...give you a keystroke logger virus, whatever. Don't assume they are stupid. They make hundreds of millions of dollars like this.
This scam, the nigerian oil thing, has been around for a long, long time, long before computers it was done via mail, and some people have gotten very rich over it, so don't assume YOU are zooming HIM, HE may be zooming YOU.
PS about ebay...
DO NOT GET INVOLVED. Don't bid on something to keep others from bidding, thinking you are doing the right thing...just report it and move on. EBAY has to get their act together, you are not the ebay police, and there is a chance that you might do the vigilante thing and hang the wrong guy. Cowboy justice OFTEN involved hanging the wrong guy. Report it and move on. THOSE scammers also often get upset, too, and they like to get revenge.
