I think a lot depends on what the listing violation is,
some listings are removed because of things that CAN be edited,
wrong category, offsite links etc.
For violations like that, an easy way to edit & repost
makes sense.
Others, are removed because they are banned, ie fakes, firearms, knives, R18 DVD's,
there would be little point in placing listings like those in an area to enable them to be reposted.
