Kristof does good work on this subject. Legislators need to do some good work also, so law enforcement and prosecutors can also do some good work. For instance, Kristof mentions Backpage is not required to verify ages. Why not? Can laws be passed that require a $100,000 fine to a publisher for each instance where the sale of a minor is found to be the result of a paid ad? And if Backpage can be proven to have edited that ad, could laws be passed holding them criminally liable as an accomplice to the crime? Backpage should simply reject any suspect ad. How about requiring Backpage to run warning photos, names and cities of all Johns caught buying children from Backpage ads in any section where such ads have been found to exist as well as for 90 days in any new section? This is a topic which requires special and constant attention. Legislators should imagine if their own daughter or granddaughter were a victim and legislate accordingly.
