Yes they do, I have used it and automated a lot of the jobs on it Little tip : Look for the jobs that are similar like a bingo sign up or something as those jobs are normally the same and the "buyer" just asks you to post the confirmation URL and then you get paid - just send the same URL to the same ones, job done!! Same works for the email stuff, just copy and paste the same email
Nah, it's against their TOS. They don't payout unless you verify your address. That involves them sending you a letter with a PIN number which you enter into a webpage. The site is still pretty good though. I've never had any problems with payment.
