The above link is a recent article regarding a 2013 hazing ritual that included exorcism.

An exorcism and a slap-down were part of a "cult-like" hazing activity in which students took on "alter egos" at William Paterson University in 2013, according to a state appeals court decision.

The court described those activities by what was apparently a small, unofficial group of students in its ruling Monday, as it denied an appeal filed by two students, Jedediah Rockwell and Krishani Nadarajah, who were found responsible for hazing, and in one case, assault, by a university hearing board. Their appeal sought to overturn the results of the hearing.

Both students were disciplined and one was suspended following the hearing, the court said.

Both denied any wrongdoing, but said some non-violent "rough housing" was part of their role-playing games. Rockwell admitted at the hearing that the group did conduct "some kind of exorcism or 'meditation session,' " the court wrote.

The board's action followed reports of "cult-like" activity filed with police at the state university by an unnamed female student, who said she had been the victim of hazing, assault and an exorcism in April 2013.

Ok so what Greek org. is guilty of this stupid ritual?
