Ravi Bopara, Alex Tudor and Chris Tremlett all chimed in after Shah's Twitter attack, and none of them were on his side.
Root was the only English batsman to pass 50 in Adelaide, scoring 67 in the second dig.
His classy innings came to an end early on the fifth morning when he edged Josh Hazlewood to Tim Paine behind the stumps and he was devastated not to carry on the fight he showed in tough conditions on Tuesday night to give his side a sniff of victory.
The innings was another example of Root's failure to convert a half century into a triple figure score. A poor conversion rate is the biggest question mark over the English skipper, who has now scored 34 Test fifties but only 13 hundreds.
Compare that to contemporaries like Steve Smith (21 fifties, 21 centuries), Virat Kohli (15 fifties, 20 centuries) and Kane Williamson (25 fifties, 17 centuries) and Root falls behind in the conversation of who the best batsman in the world is.
