Posters for the group Identity Evropa first appeared on at the university’s main campus last weekend and were promptly removed, according to a WSU email sent to students Wednesday. The university believes the posters — which violate the school’s poster policy — were displayed in an attempt to recruit new members for the organization.

Both the Southern Poverty Law Center and the Anti-defamation League identify Identity Evropa as a neo-Nazi organization. The group is known for having posted signs on other college campuses in recent years, including the University of Cincinnati.
