From the comments here and the answers and comments on Michael Hampton's post about Admin panel questions, it seems pretty clear to me that:

 - we have broad agreement that those sorts of questions are usually off-topic
 - the vast majority of the questions Noob closed (possibly all, but I don't think  multiple people are going to go through the whole list and check them all) were, in fact, off-topic.

So at this point, it seems like all that's needed is for Noob (and possibly other mods) to agree that before undertaking any big clean-up effort they'll make a meta post about it to let everyone know what's going on and give people a chance to comment.

Soon, hopefully?
