Megatypers

The website I mentioned previously that isn't a PTC, is MegaTypers. You could use the invitation code 6RPB so you could sign-up (Note: You cannot register unless you have a code when you sign up).

All you have to do here is type in captchas, just like with the screenshot below:

There are different rates per 1000 images typed depending on the time of the day. Unlike PTC's where you have to wait your ass of for an advertisement to be viewed, here you can type and type and type till your fingers just go raw. Although "typing" may seem like a far cry from "doing nothing", just think of it as a typing game :) As I've said, this is different from a PTC.
