I recently found a guy mass-plagiarizing tag wikis. The problem is, he had more than 2,000 reputation and thus a moderator couldn't manually ban him from suggesting edits.
This manual ban is useful for just making someone stop what they're doing now, so we can pick up the pieces, regroup, and send a 'real' message to them later.
So, my request: Allow moderators to manually ban users with >2000 reputation from suggesting edits, just like we can with users <2000 reputation.
