Thread order based on the last post
Since I just had an amusing situation involving a thread being revived by a spammer and hanging 'round the top of the thread list after spam-post has been dealt with, I'd like to suggest, if possible, for threads to order themselves based on the date of latest non-hidden/deleted post together with the thread rearranging itself to fit that rule, avoiding random thread bumps.
Obviously, sticked threads should be exempt.
Not a big deal, but can cause some confusion or make people who didn't notice the date, like yours truly, to make an answer regarding topics that are somewhat outdated. Plus, it simply makes the forum less messy.
