The names of four male Columbia University students are repeatedly appearing on bathroom walls and on fliers at the campus by someone alleging they are "sexual assault violators on campus."
The list first appeared last week, according to The New York Times. It was removed, but has since been redrawn on walls in other women's bathrooms and handed out on fliers headlined "Rapists on Campus."
The fliers say the school has found the men "responsible" for sexual assault.
A group of students filed complaints with the federal Department of Education's Office of Civil Rights last month alleging the school has mishandled claims of sexual assault. The students alleged that school officials tell students who file claims that they can't talk about their cases outside campus.
It's not known if the two are related.
One of the women who filed a federal complaint last month said Thursday she didn't know who was behind the lists but supports the idea.
"We want these rapists off our campus," said Rakhi Agrawal. "We want everyone to know who these people are so that they can keep themselves safe."
The university said Thursday that "graffiti is routinely removed by facilities staff," and said it had no further comment "on the particulars of disciplinary proceedings regarding sexual misconduct."
Students had mixed opinions about the vigilante campaign.
"That's probably well-deserved frustration, I just think there's other ways to handle it," said Alex Carames.
