I've actually discovered that you do have some cover for the topic titles, but it has a very strange behavior.
- Enable 'Pre-submit validation and restriction'
- Enter a banned word as the title for a new topic
- You are shown a blank page with an error message. This has no buttons of any kind. (see attached)
Is this the expected behavior? I would have liked the user to have a chance to edit their post, but its completely lost.
Additionally, you can get around this blocking, by not entering any content for the post. In this case the post with the banned word title is created after a warning of no content. This is not good!
