I bet that the unsuspecting Mechanical Turk workers, who traded their 6000 Stellars, did not realize that this was a one-time deal, rather than a repeatable revenue opportunity.

Mechanical Turk workers are used to low-paying and high-volume jobs. The $1.00 fee is very attractive for the steps involved, if this was a repeatable job. It's only natural to assume that every worker would attempt to create another Stellar account and retry the steps anew, only to be confronted with a an error after the first attempt.

And, unbeknownst to them, if Stellar does become a success, those workers will forever be left on the sidelines. Considering that Stellar has the potential to include the world's underprivileged into the global economy, often without bank accounts or identities, it's a shame that we are the first to take advantage of them.
