Bob, you asked a question on closed threads, one I have seen asked several times by you in the past.
Speaking only for myself, I think I have asked for one thread to be closed during the time since not being a moderator here on the CB. That was less than a month ago.
I made one post, expressing a personal viewpoint of mine regarding a news item. The thread was subsequently taken over by a poster for a personal agenda, in a very arrogant and demeaning manner. It was sad to see many posters beaten up on over a two day period in such a focused, self-serving manner. I left the thread alone, having only posted the original statement of my personal opinion, choosing to not defend it in any way whatsoever. I was only making a statement, not an opening salvo for a debate. Had I wished to debate, which I did not, I would have posted it on the Debate Board, better suited to those types of discussions. Discussion is fine on the CB, I do not think arrogant, self-serving, hurtfulness is, JMO.
Only after several female posters were degradingly and demeaningly talked down too, in a very derogatory manner, in essence saying they were no better than the street trash or scum that this this particular poster may appreciate, I asked for the thread to be closed, and it was. Closed, not for the arrogant stand of agenda promotion that a poster, making almost 20% of the over 100 replies on the thread, but rather I refused to be an adjunct to a platform for a 'person' to demean and degrade women here on the DIS. I have my morals. If some others don't, that is fine, not mine to tell them to. But something I post won't be used to further their self-serving and self-centered debauchery, if I have a say in it. As Pete has it, I do have a say, and I asked for it to be closed.
