This is the creepiest. A British man who pretended to be Justin Bieber to fool children into sending him sexually explicit videos was sentenced to 14 years’ imprisonment Tuesday. Robert Hunter had collected more than 800 videos from boys and girls across Europe and Asia and from as far as Tasmania. The 35-year-old tricked hundreds by claiming to be Bieber and promising to be their boyfriend. The judge called it “almost sadistic exploitation” and perhaps the worst case of Internet child sex abuse he'd ever seen.
