Perhaps before we all grab our pitch-forks and torches, demanding a trail by mob to determine if this witch really did turn someone into a newt, we can all simply assume this was a rookie mistake by someone not familiar with the intricacies and etiquette of social forums, and simply request they refrain from such action in the future. Perhaps even by PM.
But, then again, you know me. I always liked a good witch-burning, especially when the case for their witch-ness is proven because they weigh as much as a duck (which means they must be made of wood. Watch "Monty Python and the Holy Grail" if you found these references confusing.)
Or, like the Constable in "Young Frankenstein" said: "A riot is an ugly thing....
And is about time WE'VE HAD ONE!!!!" (of course, he said it in an outrageously fake German accent)
