Gangster Greed
Its a bit easyer then Cash Crate and has alot of fast easy offers.
They also pay per PayPal as soon as you make over 10$ wich is pretty nice.
So far from my experience some of the offers take a very long time to aprove.
And alot of offers never aprove. But they got so many 1 second simple email offers that its hard to pass up.
If you want to check it out for your self go to Gangster Greed
(small Update here: I learned that some of the enter your email ones you have to confirm by clicking a link in your email. Also its usefull to get a few different email adresses to get credit for multiple similar ones.)
