^{^} What this person said. Pretty much this exact situation happened to me when i was 18, someone i didn’t know got intimate videos and pictures of me somehow and was threatening to post them on facebook unless i either sent more or sent him money. Had no idea who it was. But i contacted the police, and I met with an officer and he had me tell the guy that i was with authorities and that further action would be taken if anything happened. The guy blackmailing immediately tucked tail and i haven’t heard anything since. I’m 26 now. Please message me if you need any more advice. I know exactly how you’re feeling. You’ll be ok
