Thanks for answering some of my questions.
I could not fined your instruction about removal of threads.

You or Nigel, have still not answered my question. So l will ask another one or two.

How is the removal of a thread formulated?
Do you Nigel, have the final say to remove a thread if a request has been made to remove it?
If a request has been made, and your refuse to remove it? Do you have to give your reasons?

I would thought in a democracy you would have to. :-/
