Does Banning Yik Yak at a University Violate Students First Amendment Rights?

With the many applications on electronic media we the people have the access to promote our speech at any moment. Some applications require you to create a profile, so your speech is not private in this case. The new app called Yik Yak allows users to post a small anonymous status within a small range of miles. Other users can see these updates and decide whether they would like to up the status, or down the status. When a status receives five downs the statement is removed from the news feed. 

The applications received amazing reviews right away, and was just awarded the 2015 TechCrunch award for for fasted rising startup. The only problem with this application is that, the users are allowed to say whatever they want because it is anonymous. At a few University's across the country the school boards are begging to consider banning Yik Yak at the campus. Now the schools are treading dangerous waters here as I'm sure they know the First Amendment of Freedom of Speech. 

The universities I'm sure know that this violates students First Amendment Rights, but that doesn't mean a private university can't ban the application. These rights only apply to public universities, and private universities can even develop a speech code if wanted. The government cannot punish a private university for breaking constitutional rights. This will make the public universities really think before banning this application. They know that if the students want, they can fight for the right of Freedom of Speech.
