Well personally (as I've said before) I've had at least three posts that I can recall deleted that I haven't a clue what I did wrong. For all I know, I did the same thing wrong in all three. If I were told why after the first one, I wouldn't have done it two more times.
But even so, is it so hard to when locking a thread to say "I don't think this discussion is going anywhere" or when you delete a thread to send a private message to the user to explain why. It doesn't seem like much to ask to me...
