These volunteer sheriffs of Twittersville and unauthorised constables of Zuckerburgh have now been deputised as the Bute House palace guard. They infest social media like the ants which sally forth to defend the nest - and the queen - from any perceived threat. And you don't have to do much to be perceived as a threat. All it takes is one slightly awkward question. I have hundreds of them! And I will not wheesht until I get answers!
