I'm pretty sure that Toluna are one of the lowest paying survey sites, if you work out points to time. Plus with all of the late screen outs, it makes time spent even less lucrative. They are also very fond of closing your account just as you reach payout because you have broken some rule or another, which when pressed, makes no sense at all - they did it to me. I managed to get the £35 owed and closed my account. If you check them out on trust pilot, they have only 1/5 stars.
