If the post is not reapproved after your appeal, it is almost certainly not appropriate for Danbooru. If you would like to understand why this is, you can post in forum #45532, the upload feedback thread, to get more detailed information about approvers' feelings about a deleted post.
About the deletion appeal thread and the feedback thread:
I have seen posts in the feedback thread get reapproved, so if posts which are not approved upon appeal are then posted in the feedback thread, they are practically appealed twice. Is this intended?
@Log: They're supposed to get a reason why it has NOT been approved, yes, not have them reviewed a third time. If the pictures were good enough for approval, the user shouldn't need to wait a few days and appeal again in the feedback thread to have it approved. (and if they want a reason, they will probably skip the appeal thread and post directly in the feedback thread)
