there ain't no such thing as a free lunch

I have great fun trying to hunt out the scam in those offers like "you've won £xxxx, a free holiday, a car or a caribou" this one, free ipods took a little more time than usual. It seems that YES, you can have a free ipod, if, and I quote from some deeply hidden small print :-

"After a user signs up with our website and successfully completes an offer, they must get 10 people to also sign up with our website and successfully complete an offer to get their free item."

Don't think I'll be doing that, then........
