I wonder if users get a notification that their posts were edited by a moderator just like a personal message notification when posts were deleted by a mod.
I have reported many posting violations so far from many different users - such as multiple posts in the same thread. In these cases - when moderators deal with it, they always leave a note written in red at the end of the post like
"this post has been merged by mod xxx"..
Merging posts are okay, as it only "merging" multiple posts in a single post. But the one on the thread mentioned by hosseinimr93 is different, there's no note for merging posts, the mod just edited the post for some reason.
