A first step might be to disallow upload of certain easily detected
errors (e.g. self intersecting version=1 ways with coastline tags)
either in the editor(s) or in the API. This is certainly not going to
magically fix all coastline problems but it will lessen the workload of
the "advanced" mappers who try to fix coastline problems.
