All editors have reverted a vandal, looked up his contributions, and found
dozens of other edits. Sometimes not all of the damage has been undone by other
editors, forcing a careful checking of the history of all the articles the
vandal recently edited. Whenever I follow a link from the a vandal's
contributions profile, the instance of vandalism may be the current version or
another edit may have follow. Not wanting to allow an instance of vandalism to
be buried, perhaps, by legit edits, I click the next edit link just to be sure
the edit which follows is a revert. Doing this adds up if I am check 10+ edits.
Wouldn't it be great if in the contributions profile, there could be a mark next
to any edit that indicates an immediate rollback? It would be easy to implement
(either by checking if an admin clicked Rollback, or if the article that was
edited and submitted was a version that pre-dates those edits).
