Don't click on links to purporting to offer surveillance video of Eminem being stabbed four times by a crazed fan.
The story is false, the video doesn't exist, and the links actually redirect users to scam websites promising "free prizes" (which don't exist either) for completing an online survey.
Worse yet, users who comply with instructions to share said links via social media will suck their Facebook friends and Twitter followers into the scam as well. Don't do it!
An identical scam claiming Justin Bieber was the victim of a stabbing attack made the rounds in 2011. Even the photo was the same.
