Odd that they even try and bother. Exactly what do they think are going to accomplish? Do they envision themselves as some clever and brave double agents, infiltrating "the enemy" and then taking it apart from within? Very odd.
Let me take the opportunity to say that I do appreciate you having me as a contributor to your pub (even though I haven't actually been contributing much -- too busy with crazy politics stuff lately). When you added me, I made sure to touch base with you on what you were looking for and what would be appropriate and what might not. That only seemed to me to be just common courtesy as it is YOUR pub, meaning you have the total right to totally call the shots on what is in and what is not. Someone objects, they can start their own pub.
So, what they are doing is not only rather stupid but actually, rather just plain rude.
