There are instances that some topics are deleted, either by its maker or by the moderators. Meanwhile, locked topics only stays on what section/board it was posted. And the fact the it was locked, it will only be pushed down by the most recent topics. Though some weren't deleted, moderators often move those topics onto Archival or Off-topic (if the post was indeed off-topic in the section it was posted)


You can still view locked topics yet no one can bump nor reply onto it depending if the thread poster unlocked the topic to provide an update (if and only if he locked it in the first place). Meanwhile, if moderators locked your topic, you cannot do anything at all (but AFAIK you can delete it)
