When you delete a post or move a thread out of your jurisdiction it usually auto handles them anyway.
Deleting a post, yes. Moving a thread, no. It hasn't been handled, the report just disappears from your queue because the reported content is no longer in a section you moderate. In these situations, the report could be handled before reloading the page, or before moving the thread (after checking the validity of the report of course).
Ah, right. I usually click 'handle' before I make the action anyway, but thanks for the clarification..
