Q&A for those who study, teach, research and apply economics and econometrics
-- 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)
-- MaxReputation: Max reputation to show up in results
-- DateRange: How far into the past should the query look in days (May cause performance timeouts >800)
-- MinPostCount: How many posts have to have been upvoted in the same timespan to report in this query
-- MinUpvoteCount: How many upvotes have been gained in the same timspan to report in this query.
-- Sensitivity: How close do the votes have to be together to be counted. More means less restrictive.
-- MinUpvoteCountUnsensitive: How many upvotes have to have been generated if the upvote count doesn't match the upvoted posts count.
-- MinPostCountUnsensitive: How many posts have to have been upvoted if the post count and upvote count doesn't match the upvote count.
-- MinReputationGained: How much Reputation does the incident have to be worth to be considered.
