I'm waiting for proposals for freeing them from the blackmail and threats and ensuring that they are in true control of both their documents and their 'earnings'.

taking it to the limit and making the penalty for pimping public execution, confiscation of all property and the distribution of it to your victims would work, no?

Harsh punishments against pimping would help drive it underground, but its effectiveness is still dependent on getting the evidence.
