Some college students in the United States are doing something that was once unheard of―reporting other students who attend parties.Many schools are barring parties and some other social gatherings in an effort to slow the spread of COVID-19.They are also requiring social distancing and face masks, among other rules.At the University of Missouri, one senior-year student is publishing pictures and videos on a "University of Misery" Twitter account.The images show students gathered in large groups at swimming pools, outside bars and other places. Most of the students are seen without masks.The university has a form on its website where violations of the school's COVID-19 rules can be anonymously reported.But the University of Missouri senior says that publishing such information on Twitter "adds a different level of accountability."Christian Basi is a spokesman for the university, which is in the city of Columbia and has about 30,000 students.
