The fuller answer
Sextortion is a threat to share sexual images, information, or fabricated content unless someone sends more images, pays money, meets, or obeys another demand. The blackmailer may act like a romantic interest, hacked friend, peer, organized criminal, or trusted person.
Paying or sending more rarely guarantees an end. The safest immediate pattern is to stop negotiation, preserve evidence, tell a safe adult, report the account, secure accounts, and use available image-protection services.
The young person is not the offender because they trusted someone, sent an image, or panicked. The threat and exploitation are the wrongdoing. Suicidal panic can rise quickly, so nobody should face it alone.
