Often times I will notice the same user repeatedly submitting, at least what I consider to be, bad edits such as radically changing the question or just performing some minor edit like fixing a typo or two. Is there some way to try to inform a particular user about the guidelines for making edits to try to mitigate the bad serial editing? If not, would a featured like this be beneficial?
Yes, this feature does exist. It involves leaving a comment under one of the abused posts that describes the problem and addresses the user responsible using his name prefixed by the @-symbol. Example:
@GlennNelson: please don't edit pictures of your dog into every post you read. She's a very nice dog I'm sure, but this is not how we indicate that we've read posts here on Stack Exchange.
If that doesn't work, you can flag for a moderator's attention - they'll review the situation and take appropriate action.
