Apparently there is a Chain going around Facebook called
"I love you" that makes you post a
Coded message on 10 friend's Walls and, if you receive more than 10 on your profile, this means you're loved.
ALL of us are 'loved' ...if only we realised it;
It does not need a Chain with the capability of infecting Computers to tell you that
As I am sure you know, Code is one vehicle ( method ) by which infections can be spread
You should not be forced by Facebook to do anything you do not wish to do , especially sending apparently 'innocent' Code to people
