To report blackmail on Snapchat, start by saving all messages, photos, or threats as evidence. Open the chat, press and hold on the message, and tap “Report” to notify Snapchat about harassment or blackmail. You can also go to the user’s profile, tap the three dots, and select “Report” for safety reasons. Snapchat’s safety team reviews reports quickly and may suspend or remove the offender’s account. Additionally, report the case to your local cybercrime authority using their online complaint system. Never respond or send money to the blackmailer. http://theantiextortionlawfirm.com
