Happy 43rd birthday, Stan Collymore, and your birthday present from Twitter is ? uninhibited trolling. Collymore, a former Liverpool and England striker, does controversy for a living as a columnist and commentator for TalkSport. He's quick, knowledgable and direct, on the air, in print and on Twitter. It's part of his job description to be provocative. He wants Twitter followers, and retweets and the whole paraphernalia of a big social media presence. But, quite reasonably, that does not include racist abuse and death threats, nor a disregard for the law. And if it happens, he expects action. But from Twitter Inc, all is, according to him, silence.
