At least eight men have killed themselves after being unmasked by pedophile hunters since the trend of volunteers posing as children online started several years ago in the UK, according to the BBC.
Pedophile hunters snare people with fake social media profiles, engaging with them until the unsuspecting adult arranges a meet-up. The volunteers then inform police, film the encounter, and post the video online, where it could be viewed hundreds of thousands of times.
