The worrying rise of the Facebook flasher

The first time Natasha Harpley’s Facebook Messenger app pinged with a notification from the stranger was in November last year. She wasn’t friends with him on Facebook or in real life, but he kept trying to engage in sexual conversation, making a stream of comments about her appearance. The 39-year-old from Norwich ignored him but didn’t block him – three kids and a busy job meant she was reluctant to add another thing to her to-do list.
