Also I do see from time to time inappropriate behavior of other posters here who escape any form of punishment. I'm not someone who wants them see punished, I can tolerate a lot. So, their behavior is not what I'm comnplaining about. My point is just that you can make stupid remarks on this forum, you can launch personal attacks, you can derail a serious physics discussion in a forum by such behavior and nothing happens. Then comes along a poster like me who just discusses physics, who always sticks to physics here who never insults anyone or otherwise derails a physics discussion and he is then punished. Not once, but twice.
