ThinkuKnow has released an education resource about online blackmail for 15-to 18-year-olds which aims to help young people: identify key characteristics of how blackmail operates online; understand the impact it can have; and know how to access help if they need it. The term ‘online blackmail’ is used to refer to the act of threatening to share information about an individual (including sexual images or videos) to the public, or their friends and family, unless a demand is met.
