An executive at Yik Yak, an anonymous social media network, is speaking out after a suspect was arrested over threats made on the platform against black students at the University of Missouri.

The messages came amid heightened racial tension and protests at the university, which saw the school’s embattled president step down earlier this week.

“There’s a point where discussion can go too far – and the threats that were posted on Yik Yak last night were both upsetting and completely unacceptable,” wrote Brooks Buffington, co-founder and chief operating officer of Yik Yak, an anonymous chat app popular on college campuses, in a blog post. “Let’s not waste any words here: This sort of misbehavior is NOT what Yik Yak is to be used for. Period. It is not condoned by Yik Yak, and it violates our Terms of Service.”

The suspect’s arrest came after a Yik Yak user threatened to “shoot every black person I see” at the college, amid other warnings. Some University of Missouri professors canceled classes over the messages, while other students posted on social media about staying home for the day.

It isn’t yet clear if Yik Yak staffers helped authorities locate the user who posted the threatening messagesm but Buffington’s statement noted the company’s general cooperation with police. “Furthermore, please remember that Yik Yak and law enforcement take threats seriously,” he wrote. “Yik Yak works alongside local authorities to help in investigations, and we may share information with law enforcement as set forth in our Privacy Policy and legal page.”
