Ahhhh. That's the problem. It lets the spammer who sent the e mail know it's a valid e mail address so he or she can send more mail to it and also sell the address to other spammers generating more junk in my box.
And the gasoline isn't free. It's still $3.00 per gallon. And that's my point. But the spammer is trying to convince you that it is free. It seems to me that a lot of spam is a variation of the old slick talking shell game (which shell is the pea under).
Here's another one.
New car dealer
Say you buy a new XYZ car, and pay for it in full, up front, with $20,000 cash.
Now, it's two years later, and after two years of good driving, you want to trade it in and buy the new model.
So you drive it onto the new car lot and talk to the dealer.
And the dealer says "Sure. I've got the new model here. Your choice of five different colors. It's only $100,000 (on sale today). But . . . I see your old car there, you've taken good care of it, I can give you an $85,000 trade in allowance."
The dealer continues. "So you're getting a $100,000 car for only $15,000 cash, and getting an $85,000 trade in allowance on a car that you wouldn't be able to sell for more than $10,000 if you placed a for sale ad in the newspaper. I must be crazy. I don't know how I stay in business selling new cars so cheap."
You can cut through all the smoke and mirrors and fancy talk, by looking at what the dealer receives, and what the dealer pays.
Cash received from you $15,000
Cash received from selling your trade in car $10,000
Dealer's cost ($20,000)
So you've effectively paid $25,000 ($15,000 cash plus a trade in car worth $10,000) for the new model car that, two years ago, cost $20,000. Not a bad deal, but not as good as the dealer would have you believe.
I could go on because scams seem endless. Oh well, one more.
Attention potato farmers. I'm selling a product that's guarenteed 100% effective in killing all the potato eating bugs in your field. Only $10.00.
And, unknown to the buyer until it's received, the product consists of two bricks labeled "Brick one" and "Brick two" with instructions that read, "Place potato eating bug on brick one, and smash it with brick two."
Scams are seemingly everywhere, and even good, intelligent people sometimes get scammed.
Thanks to everyone who replied, and that explains a significant part of the spam in my box.
