-- This is a query that attempts to find serial upvoting on Stack Overflow
-- Results returned by this query are fairly accurate but should not be
-- taken as concrete proof that serial upvoting has occured. If you're
-- going to flag based on this query's results, double check every single
-- case beforehand. This is not a tool to be used for witch hunting. Serial
-- Voters are for moderators to deal with - do not use this as a way to
-- publicly air other people's dirty laundry.

-- Version 2.3 (reduced link brittleness, linking back to SO as per request)
