It would help if the forum could detect the offending content right at the time the user clicks on Reply, and fail it then and there if it does not meet the guidelines.
Some replies are removed after they are posted and accpted, leaving the post in an indeterminate state which says that a reply has been accepted but which doesn't display the same reply.
Edit: May be also add a user-visible notification/counter about the # of times a post/reply can be edited before it becomes eligible for blocking.
