Each worker on Mechanical Turk is anonymized using a string of alphanumeric characters which protects the identify of the individual, but also uniquely identifies a worker. This “code” can be searched and parsed once data is returned. While it is possible for individuals to have multiple accounts, creators of online labor markets i.e. Amazon, have strong financial incentives in place to prevent users from having multiple accounts. All major markets use some combination of terms-of-use agreements and technical approaches to prevent multiple accounts. Amazon for instance, requires all workers to submit their Social Security Number in order to track tax remittances to the IRS, thus making multiple user accounts nearly impossible. Multiple accounts will surely exist, however, the relative scale of users abusing the service of online labor markets is greatly outweighed by its benefits.
