There are two posts on the front page of Anime.SE that don't seem like they should be there.
The second post in this image is four months old. It could've been bumped by Community - but if it was, the "modified yesterday Community♦ 1" thing is missing. (We have some posts further down on the front page that were Community-bumped, but no posts above that were Community-bumped. Was Community's behavior changed in the last day or so?)
The third post in this image is more than two years old. I don't think it could have been bumped by Community, since it has an upvoted and accepted answer. Which raises the question, then, of what it's doing on the front page, despite not having been modified in two years. Also, the
.started div doesn't have the word "modified" in it, and probably should.
Neither post has any activity recently (including deleted answers).
This is all a bit weird. A bug, mayhaps?
