My ex has posted inappropriate pictures of my son and his brother sitting on a bed in their underwear reading a book. This picture is a part of his profile and is the background image. I don't want a picture of my son in his underwear anywhere on the internet there's way too many sickos out there. I need it taken down but he is in prison. So whoever posted this also changed his profile picture. And the only thing that I can say is that it is his new girlfriend that posted these pictures or somebody hacked his account. He's been in prison for months there's no way he could access his account. I told him about it when he called and he denied knowing anything about it. This image the picture my son and his brother needs to be taken down immediately I reported it to Facebook several times and they will not take it down. It has to be taken down whoever posted it didn't have my permission or Gerry's permission. It's sick.
