I have noticed an inconsistency between the number of comments actually present on a post and the number declared at the beginning of its comments section, the former often being one less than the latter.

For example, of the seven discussion posts starting at "Pascal's wager" and working back, the "Pascal's wager" post at the moment has 10 comments and says there are 10, but the previous six all show a count one more than the actual number of visible comments. Two of them say there is 1 comment, yet there are no comments and the text "There doesn't seem to be anything here" appears. These are meetup announcements that I would not expect anyone to be posting banworthy comments to.

There is no sign of comments having being deleted or banned, and even if something of the sort is what has happened, I would expect the comment count displayed on a page to agree with the number of accessible comments.

On the Discussion page itself, the comment count displayed for each post agrees with the comment count displayed within the post.
