I am also facing this problem because:
- User A replied to the topic and then replied again pointing out a typo in his previous post
- Admin replies pointing out that posts can be edited
- User A fixes original reply and deletes the second one (it is now marked as “will be deleted within 24 hours”)
- Admin also deletes his post
In my case that is not enough of an explanation. Firstly because I have previously definitely read all posts before they were deleted, so it should be known that I read them. Secondly because the post at the bottom (which is deleted) is currently my own, so it is by definition read by me.
In any case: wouldn’t it be a solution to just assume that deleted posts have been read (instead of assuming that they have not been read, as it is now)?
