It is good to see that the ban is being enforced. I guess it is obvious that someone who has an irresistible impulse to reply to a topic in vortex with a political rant, could just change the To: field to vortexb. The topic, converted to a political rant, would continue in vortexb with a life of its own, while the original topic would stay in vortex.
And anyone who is a political junkie would be subscribed to vortexb anyway, so nothing would be lost to him. Maybe people don't do that simple thing because they can't separate politics from science and are unaware when they go from one to the other. The recent rustications may concentrate their minds, however.
