Mods locking/closing threads with no notice.

So, every once in a while I see threads that were randomly locked/closed with no reply from the moderators. (I just saw one regarding a hacker called “M0nst3r” I think was his name). Could the moderators at least mention why they lock threads? Wait, scratch that, can we at least know who the moderators are?
