I can remember this happening years ago on Fb. Every day for like a week, it was just awful images of dead African children, dying children, and gruesome animal cruelty, such as a dog owner skinning the entire dog alive and putting it in a salt field, and another that cut both his dogs ears off and laid it in front of him while taking photos as he looked down at his own ears. Truly horrific stuff that messed me up. And that was nearly 10 years ago.
