I dont know of anything formal. Though I could suggest some type of change profiling system. Something can flag edits out character for a bound box. Development Seed just demoed some related tools at this year’s StoM US.
It should be able to notice drastic changes to more established areas. Especially things like
name changes to places or streets. Multiple additions and deletions of ways in a single changeset might be sogn of vandalism. It could just warrant a message to a new mapper explaining why the practice is considered a bad habit.
