We'll be developing tools that take advantage of the revision scoring service to help editors revert vandalism and identify good newcomers in need of support.
Test out the scoring service: http://ores-test.wmflabs.org/scores/enwiki/?models=reverted&revids=638307884|642215410
See https://meta.wikimedia.org/wiki/Research:Revision_scoring_as_a_service for a description of the service. See also https://www.youtube.com/watch?v=53bG9mYMYE8#t=11m30s for a recent presentation on the scoring system.
