The only good thing I can say about it is that you can reap a good sum. if you make a cumulative amount of errors over time, your account will be suspended or banned . sometime the system will give you an error and warning even if you actually did the captcha the way it was supposed to be typed in . the system just brought up a mistake that was falsely given to me a while ago and suspended my account for 20 minutes .i was a good worker and mainly made mistakes as a beginner . I refuse to continue using this system and eventually get a long suspension or a permanent ban through of no fault of my own.
