As I have disabled edition/deletion self post by members, I don't have that issue with general members.
But, the problem I am facing is, Mods can (soft) edit/delete anything, including their own. As it seems, the deletion of own post/thread by a Mod can be tracked in Moderator Log. But self post edits by the Mods are not logged anywhere. So, I was thinking of a place where I can track self-edits by the Mods.
