Or else..

“Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by an train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." George Orwell - 1984

Isn't it supposed to say, "Think before you post, 'The UK government is shit!'."?

Never!
