FB is a great big platform. Of course they are going to be targeted first. Especially since they have the ability to stop the problem, just as the classified editor at a newspaper can decide, "No, I won't run this ad that says "No Blacks". As that would be a bad idea for both myself and the newspaper given the laws on the books that everyone knows about."

Given a finite amount of law enforcement manpower, it makes sense to target the pimp first. Especially if they are national in scale and flaunting it.
