Yes!!! I know a brilliant Psychiatrist who would pose as a child on the internet. He did this as a hobby. He'd attract pedophiles. Eventually he learned everything about them. He compiled his work and sent it to the media, politicians, and the press. Eventually he became the expert on a new show called to catch a predator. He always said his moment of triumph was when he sent the pedo a photo of the offender, his address, a list of legal charges, a full list of messages and texts, about 3 minutes before the police were knocking on his door.
