This has been tried before
Anyone remember AllAdvantage.com and similar back in the bubble 1.0 days?
They paid you to watch adverts, so people wrote something called Trembler which moved the mouse around the screen so that it would appear that you were watching adverts for the maximum permitted number of hours per day.
The only difference is it that they are paying in vouchers that are theoretically exchangeable for cash. So you set up a virtual machine to "watch" a load of adverts and earn a load of batcoins, write some rubbish in a blog, and pay yourself to read it.
