Smith scored 17 596 runs over all three formats of the game - Test, ODI and T20 - for South Africa before retiring in March 2014.
Smith's critic got involved in a "twar" with the former Proteas star after he was pictured sharing his batting skills.
But with this persistent "fan" getting the last word in, Sport24 wants to know: Who really owned who?
