To the letter of the rules, no one has.  But in the spirit of the rules, I think we've all been guilty at some point.  Myself included.  There's no denying it's fun to speculate.  But it's also irresponsible and could have serious repercussions.  Whatever is decided, rules-wise, I won't be playing any further part in these guessing games and would strongly encourage others to do the same.
