A long-running hoax has resurfaced among Facebook users, urging them not to accept friend requests from an account called Jayden K Smith.
The well-meaning message warns friends and family that Jayden K Smith is a hacker who will gain access to your account if you accept their invitation.
It says Smith is a hacker who 'has the system connected to your Facebook account'.
Although some users of the site do add strangers for nefarious purposes, in this particular case the chain message is a prank.
