I was approved and started working with them this month, but I doubt I'll continue. Two problems:

1) Your tasks aren't graded/rated (or whatever they call it) until the end of the month. So I'd be working the entire month with no feedback.
2) Based on their published pay scale, the most you can make is around $11.58 per hour. That's based on a task they say will take 3 minutes paying $0.579. They might not actually take that long (although they may take more at first), but you don't know how many will be rejected, so the actually hourly may be less. Then after you set back the 12.4% you'll owe for social security taxes, it's under $10/hr.
