What automatic moderator? All posts are manually reviewed. There are no thresholds, a post's score, favorite, and comment count have no bearing on whether it ends up being approved or deleted.

There's a new automod that deletes after 30 days have gone by, along with the Automatic Removal: Does not meet minimum quality standards (In approval queue for 30 days.) reasoning, I've noticed some of my unapproved images in acceptance limbo have been deleted by them. They're a relatively new account, created in August, but the auto deletion via being 30 days in queue is a new action from them.

Anyways, it seems to be a new way the mods are clearing out the approval queue backlog; my guess is that perhaps it's there if mods are conflicted about an approval and can't come to an agreement to approve or delete.
