There's a bigger issue of celebrities with large followings tagging people they don't like in their Tweets, a comedian did it to me once, it was completely out of context and not what I'd intended but then all his sycophantic followers started having a go at me, I just ignored it but realised that a good proportion of his tweets were the same, David Baddiel, I realised, is the same, it's basically a form of bullying that they would be horrified about if they treated similarly, there's no opportunity to come back because any response is lost in fawning retweets and further mislead abuse.
