-- Simple query to identify people getting serially downvoted

-- Version 2.0 ( Added Parameters to make search functionality configurable )

-- DateRange: How long should the query look back in days? High amounts can cause timeout.
-- MinPosts: How many posts at the minimum have to have been downvoted?
-- Sensitivity: How close do the downvotes have to have been to each other? More = Less restrictive
-- MinDownvoteCount: How many downvotes does a post have to have recieved to be considered
-- MaxDownvoteCount: How many downvotes can a post recieve before being no longer considered
