See [this answer here](https://meta.stackexchange.com/a/137334/155826), which addresses the problems of having a lack of useful feedback to users whose suggested edits on questions and answers are rejected by the community, and which provides some possible solutions to providing this feedback to users who suggest these edits.

The main idea of this answer is that the rejection notice should appear to the user before they make the mistake again. For tag wiki edits, this could be displayed as a banner above the tag wiki edit screen (but not as a notification, which we've established is reserved for "You rock!" type messages):

The same feature request for suggested edits on posts should apply equally to suggested edits on tag wikis. Feedback is important in coaching people and providing them with the necessary guidance to change or improve a specific set of behaviors, even if those actions are currently conducted in good faith.

In cases where a user could be suspended for too many rejected edits, this feedback is critical.
