I got on Facebook tonight and I had a ton of DM's and they all said the same thing:

Please tell all the contacts in your Messenger list, not to accept Jayden K. Smith friendship request. He is a hacker and has the system connected to your Facebook account. If one of your contacts accepts it, you will also be hacked, so make sure that all your friends know it. Thanks. Forwarded as received

It's another Facebook scam that says this guy is a hacker. People get scared of these all of the time (I don't blame them--you never know when they're going to be true, sometimes), but this one has been told it is not true, so don't worry!
