As I write this, Moon Man has just stated (over in the conspiracy theory forum) that he is drunk. He then asked where the "alleged vacuum" around the moon ends and asked why space ships don't create sonic booms.
With this, it became crystal clear to me that he was a troll. Everybody, even 5 year old children, know that there is no air in space. The only reason for a person to suggest otherwise is to troll. Toseek correctly identified him as such and banned him, and I really regret that I didn't accept toseek's judgment. I feel a little bit guilty about it.
