I got information from somebody and you all should know for your own accounts' safety.
Here's what it says.
"There is a hacker will be going around and post pornographic pictures to your gallery or on your page, including a male's nether regions (please explain this part); that is if he hacks your account. If he finds that you've posted this to a journal or on your page, he'll know you know what's going on and won't hack you. Please copy this for your safety to prevent your account from being hacked. THIS IS NO JOKE."
If somehow the hacker manages to get into your accounts, don't hesitate. Report this at once. Thank you
