Syracuse "suspends Theta Tau fraternity after video of ‘extremely racist’ behavior surfaces"

“Five Theta Tau brothers have anonymously filed a lawsuit against Syracuse University after offensive videos surfaced of a fraternity event.”

The men accuse SU of “branding them as racist, anti-sematic [sic], sexist and hostile to people with disabilities,” in the aftermath of the videos, according to the complaint filed in federal court.

The brothers say they were suspended from school, barred from classes and maligned “to salvage Syracuse University’s reputation” at their expense. They said they were subjected to “ridicule and scorn.”

I’m pretty sure all that is the obvious consequence of participating in and filming those videos, not anything Syracuse did. They “branded” themselves with their actions.

So, under what circumstances are plaintiffs allowed to be anonymous?
