Within an hour, Boren responded.

By the next day, the university had closed down the fraternity chapter and ordered students to vacate the house.

The student group could have taken the video directly to campus authorities. Releasing it on Twitter instead amplified the outrage that resulted in swift action.

Kappa Sigma fraternity, University of Maryland

University of Maryland president Wallace Loh turned to Twitter on Mar. 13 after a racist, sexist email allegedly sent by a Kappa Sigma fraternity member last year went viral. Soon after a screenshot of the alleged email began gaining traction on Facebook and Twitter, the university put out an official statement saying it was investigating the matter.  The legal ramifications of the email are still debatable—some argue that it falls under free speech protection—which can restrict a university’s actions against the fraternity or the individuals. Nevertheless, Loh used his official Twitter account to speak his mind about the incident, expressing his personal dismay.

Kappa Delta Rho, Pennsylvania State University

Pennsylvania State University’s Kappa Delta Rho fraternity is being investigated for allegedly setting up a private, 144-person Facebook page that included photos of naked women asleep or passed out. The university suspended the chapter, after a fraternity member printed out paper copies of the page and showed police what was happening in January according to the New York Times (paywall). The school announced the launch of a task force to review Greek system misconduct on campus.

Sigma Chi, Westminster College

The national Sigma Chi organization conducted an investigation into the Westminster College chapter in Missouri earlier this year, and punished members for hazing and other violations in January. The fraternity was then suspended indefinitely and a college investigation launched after a member showed administrators screenshots of a private fraternity Facebook page with “offensive material,” university spokesman Rob Crouse tells Quartz.
