Get paid to read emails!

This is what was the subject of an email that came to me from somewhere. Out of curiosity I went to the site. There are so many promises. I was a bit sceptic as I do not believe in someone throwing you easy money. But this site ConsumersIndia.com is an Indian site. It is supposed to be operated from somewhere in Kerela. In fact I could find few more such sites afterwards. Can clicking on emails be really productive? The trick followed seems to be easy. They will send you url of some advertisements, like the ones of google adsense. If you click on the ad link, they get paid and a small fraction of this is credited to your account. It seems easy, but the catch is that it may take years for you to get paid. They may get paid in dollars, but you will be paid few rupees, say Rs.5/-. And who knows when the site may close shop! Your comments are welcome.
