A former Virginia Tech student who posted a violent threat on Yik Yak has now taken a plea deal to avoid further jail time.

Back in April 2015, Ki Ung "Eddie" Moon posted to the notoriously anonymous social network, "another 4.16 moment is going to happen tomorrow. Just a warning." That date, April 16, refers to the shooting massacre that happened at Virginia Tech on April 16, 2007 when 33 people were killed.

Not long after, Moon turned himself in to the police, where he initially faced criminal charges of harassment using a computer. According to the Roanoke Times, that charge was changed to disorderly conduct as part of an agreement with local prosecutors.

A judge handed down a sentence of a year in jail, including 11 of those months suspended. As Moon had already served about a month in jail, he was believed to have been released on Thursday. Moon also will remain on probation for two years and is banned from the Virginia Tech campus during that period.

Though Yik Yak allows users to post anonymously by default, many users have learned that the service is not truly anonymous—the company has complied with police requests for user data (including GPS locations and IP addresses) on multiple occasions.

Most investigations have revolved around threats and harassing posts that have circulated at high school and college campuses, where the app has enjoyed popularity due to its "anonymous with GPS" functionality—meaning, users at a school can post on Yik Yak to ensure that people within that immediate vicinity, and nobody else, see the posts in question—essentially, like a virtual bulletin board in the school cafeteria.

Last month, a freshman student at Florida Atlantic University was kicked out of his school and given a trespass warning after talking about a possible gun-attack threat on Yik Yak.
