Amazon Mechanical Turk is a service where people can do simple tasks for small amounts of money. Usually things you would expect to be automated, especially in this day and age. I did it for a bit about a decade or so ago. Things like small amounts of proofreading, transcription, etc.
The name is a reference to a hoax device made in the late 1700s that was supposedly a chess playing automaton. In actuality it was operated by a person hiding within. It was nicknamed the Mechanical Turk because it had a model of the head and torso of a person dressed in Ottoman robes, etc.
