Seriously, for being a fire-and-forget API to the lowest possible level of human tasks, it requires a heck of a lot of hands on management, including
arguing with identifiable people over two cents. (YOU DIDN'T SAY TO TURN OFF CAPS. I wish I were exaggerating.)
I ended up writing off five hours to goodwill when I did a project with a $100 turking component for a client. To use a line favored by my old Indian colleagues: if you pay peanuts, you get monkeys. Lesson learned.
Next time I will just find a freelancer with a high tolerance for repetition.
