They would only appear in the moderation queue if they were set to moderated / unapproved in the software, e.g. because they were detected as spam or because you set them that way using inline moderation or because a user's permissions meant they should be moderated rather than being visible.
Is that what happened or are you implying that you set them manually in the database?
If they were moderated "normally" then they should just appear there for any moderators who have the edit any, delete any or approve/unapprove permission.
