I agree with AE. If this is truly a problem and you want to fix it so to say, donate to some women shelters that have taken in human traffic victims. Le is always working on this issue and I doubt your helping.
If your getting them shut down like you say. You may be hurting them, by making them shut them down faster than they need to, impeding their ability to find the source.
I can understand your crusade here. No one should ever be put in this line of work against their will.
Just think you should let the professionals handle it.
