I logged in to Facebook only to see this message with a link saying I uploaded a clip on YouTube and I can't remember uploading any video. When I clicked on the link, it took me to a site with Facebook interface, requesting that I input my Facebook username and password.

This is how these scammers steal people's Facebook accounts and use it for scamming. He's now claiming someone accessed his phone and sent the message to his friends.

Please be careful where you input your social media details. Always check the URL.

It happen to me too, my account was hacked and same message was sent from my account to people on my friend list... A friend got the message and called to inform me. I have to go through Facebook page to gain back access to my account. before warning all my friend not to respond to any message from my account for now.
