Totally agree.
There was a BBC article on him earlier this week looking at his story so far, which explained how he'd been let go by Kent and then sacked by Yorkshire for poor discipline and attitude, and by his own admission he wasn't taking his cricket seriously enough. He's since turned his career around and forced his way into the England setup. The tweets in question would date back to those early days with Kent so you have to assume that he's grown up since then.
Still can't get my head around how people allow this stuff to still be visible though, nor how and why someone would have the inclination to trawl back that far looking for incriminating tweets.
