My university is one of the universities listed in the article for having issues with Yik Yak. The university president was rumored to be considering banning the app, which is a functionality supported by the creators to fence off a certain geographical region. The yaks made in my area can get particularly nasty, but I'm not sure what the appropriate response should be. Most of them aren't specific enough to be illegal - inciting violence, harassment, etc.
Comments made on Yik Yak also was a big motivator for a series of protests on my campus around the time of the Ferguson protests, which is unusual for a socially conservative campus with little social activism.
