Scam posing as a link to a video claiming to show a man being eaten by a shark. Messages have appeared across the site, shared from the Facebook accounts of users who have already been tricked into clicking on the link. Instead, you are urged to share the video link with other Facebook users *before* seeing the video for yourself. Dont be tricked by the promise of a lurid, shocking or sexy video into doing the scammers dirty work for them, theyll demand that you complete an online survey.”]
