>But for whatever reason enforcement efforts seem to be more focused on censoring and deleting the images rather than on curbing the actual act of child trafficking and rape.

Paradoxically it would seem that turning a blind eye to forums that disseminate CSAM would actually help surface and prosecute physical crimes easier. There is a counter-argument that CSA happens because of some financial or other incentive for the abuser to share the material online, but that argument has always seemed fickle to me. What's happening behind closed doors will probably keep happening, whether there's a camera involved or not.
