No more Marks and Spencer e-mails please about M&S vouchers - It's a scam !

I've had three e-mails in the past 24 hours that look like this:

Subject: M&S vouchers Hi all, Marks & Spencers, in conjunction with Persimmon Homes, are giving away free vouchers. Marks & Spencers are trying word-of-mouth advertising to introduce its products and the reward you receive for advertising for them is free non-refundable vouchers to be used in any M&S s to re. To receive your free vouchers by e-mail all you have to do is to send This email out to 8 people (for £100 of free vouchers) or 20 people (for £500 of free vouchers). Within 2 weeks you will receive an e-mail with your vouchers attached. They will contact you through your e-mail address.

I'm fed up with them now.

Can people who receive them just look carefully, wonder why M&S would dream of sending someone £100 for sending eight e-mails (that's £12.50 an e-mail), and wake up to the fact that his is just spam, a chain e-mail and a scam (put which ever word you want to it).

And please, PLEASE, stop sending them to me !
