Perhaps I'm taking the moral high ground here, but you should contact the media or human rights organizations, spill the beans to help them investigate. Anonymously if necessary.

Don't let scumbags have their way, if you can tip the scale in the other direction. But again, don't want to take the moral high ground and tell people what to do.
Last I checked, they had people contact them and published material they liked.
Not discounting the work they do, but there's a huge difference between them and someone like The Guardian assigning reporters to investigate a story.
