Facebook users, if you see a blurb for a CCTV video of Will Smith dying of a drug overdose in the hospital, don't click on the link. It's a hoax and a scam.
The blurbs are generated by a rogue app designed to trick you into granting it access to your profile and friend list, which it uses to replicate itself on other people's pages.
The worst of it isn't that you're complicit in spreading a lie Will Smith isn't dead, after all the worst of it is that you've allowed the app to hijack your Facebook account.
If you've already made that mistake, go here for instructions on how to remove the app. Oh, and you may want to inform your friends about it, and apologize.
