I often see businesses running competitions to drum up more customers, things like refer xx of your friends to go into the draw to win something.

I have participated in a few because the prizes looked pretty good, such as an iPod or a free holiday.

But what I want to know.. is do these sort of things motivate people, or just attract spammers?

Do you think its the business that motivates them, the ease of the competition, or the prize?
