As I always point out to my mates, RAWK actually stands for Repetitive Anal Winging Killjoys
Name and Shame them is what I suggest.
Next to their User Name insert the word (Crank)
Given that the meaning of "Crank" is a pejorative term used for a person who unshakably holds a belief that most of his or her contemporaries consider to be false. A "cranky" belief is so wildly at variance with commonly accepted belief as to be ludicrous. Cranks characteristically dismiss all evidence or arguments which contradict their own unconventional beliefs, making rational debate an often futile task.
Universal characteristics of cranks include:
1. Cranks overestimate their own knowledge and ability, and underestimate that of acknowledged experts.
2. Cranks insist that their alleged discoveries are urgently important.
3. Cranks rarely, if ever, acknowledge any error, no matter how trivial.
4. Cranks love to talk about their own beliefs, often in inappropriate social situations, but they tend to be bad listeners, and often appear to be uninterested in anyone else's experience or opinions.
Some cranks exhibit a lack of academic achievement, in which case they typically assert that academic training in the subject of their crank belief is not only unnecessary for discovering "the truth", but actively harmful because they believe it "poisons" the minds by teaching falsehoods. Others greatly exaggerate their personal achievements, and may insist that some alleged achievement in some entirely unrelated area of human endeavor implies that their cranky opinion should be taken seriously.
Only once they “change their ways” will (Crank) be removed from their User Name.
