That's assuming the attacker would be a fellow student connecting to the wifi network, and not the school, who has full control of the the network beyond the access point. I'm long out of undergrad so I've never used this app, but I've read that YikYak is at least somewhat known for controversial content regarding schools, school employees/faculty, and fellow students. Seems like there would've been just as much, if not more, incentive for a university administrator to want to get people's post histories in order to divine who posted a particular piece of content.
