A Facebook post by “Casey Champagne”, whose secondary name on his profile was listed as “Casey Max Charbonneau” (pictured below with Hillary Clinton) and whose Facebook likes included Correct The Record and Barrier Breakers 2016 (Brock’s recently launched online operation), confirmed that Clinton trolls were behind the attack when he bragged in the Facebook group “Bros 4 Hillary” that he managed to get one of the groups banned for “containing credible threat of violence”:

Last week, Correct The Record (CTR), David Brock’s super PAC that coordinates with Hillary Clinton’s presidential campaign, announced that it was spending $1m on social media in an effort to combat Bernie Sanders’ online dominance. How, specifically? By paying trolls.

Last night, on the eve of five Democratic Primary elections—Connecticut, Rhode Island, Delaware, Pennsylvania, and Maryland—we may have seen this paid army in action. Several notable Bernie Sanders Facebook groups were taken down following a coordinated cyber attack by Clinton supporters, in which a number of users reported content on the pages simultaneously. According to US Uncut, “Facebook’s automated systems take note of how many individuals report a particular post, and if the post is reported enough, it will be taken down. This same process applies to groups, pages, and individual user accounts.”
