WhatsApp Harassment and Threats: What to Do
Repeated messages, threats or abuse on WhatsApp can be frightening. How to block and report, keep evidence safely, limit who can contact you, and when to go to the police.

Harassment on WhatsApp can come from strangers, scammers who were refused, ex-partners or people in a group. It can include repeated messages, threats, insults or sharing private information. You do not have to put up with it.
