There are employment laws in the UK which mean a Mechanical Turk-like system wouldn't be able to have jobs listed for such low amounts - I think it comes under the minimum wage laws. Because of this and similar laws in other countries, Amazon have kept job-posting MT accounts limited to the USA at the moment, which doesn't have the restriction. I don't know enough about Dutch or Indian law to know whether a similar system could be set up within them, but there are problems with rolling something like this out globally.
