What is Happening??? – WhatsApp Messenger Review

I deleted WhatsApp a while ago because I got a text from an unknown number (not on WhatApp, an actual text) saying my pictures were taken from WhatsApp (I rarely use WhatsApp so there were no pictures on it) and put on a site, which was some sort of adult content site when I clicked the link to see what the heck was up. Fast forward to today, the app has been deleted for a while but I got another message from another unknown number saying my pictures were taken and put on another site. Not only has this happened to me but to other people I know as well. What is going on and how do I stop it??
