Threatening someone, on the Internet or elsewhere, is very serious! Some actions can even be punished by law, such as harassment, physical threats, attacks on someone’s reputation, or distributing intimate images of a person without his/her consent.
Keep the evidence of the threats you’re getting. Save and print bullying screenshots, conversations, or emails. Then you can use this evidence to defend yourself.
Don’t keep these threats to yourself. Even if you’re scared to do it, talk to an adult you trust: one of your parents, another family member, or a counsellor. It will make you feel better to share your anxieties, and you’ll have support in finding a solution. Two heads are better than one!
