At least closed questions are visible and you can decide for yourself if you like them. Other moderators just delete your question and you will never know why. There is no trail, no warning and no one can be held accountable. Unless you have 10k reputation. With 10k you can see deleted questions and it seems you can see who deleted it.

I note most of those questions are basically some awesome trivia some guy discovered on the way while solving tough problems.

Or recommendations to books/reading/tools etc.
