(Update: 11 p.m.): Turning Point USA’s Professor Watchlist site is back online.

Professor Watchlist, a project of right-wing youth organization Turning Point USA that was dedicated to naming and shaming “college professors who discriminate against conservative students and advance leftist propaganda in the classroom,” appears to have been suspended by its web host.

The Professor Watchlist website featured maps and directories of instructors whom Turning Point USA staff claimed were indoctrinating university students with radical left-of-center politics. The project was launched in 2016; the list of allegedly offending professors in its directory numbered in the hundreds before it went offline. Critics of Professor Watchlist have shared concerns that the site was a “threat to academic freedom.” A professor placed on the list said he worried that being on the list would result in the targeting of him and his family for harassment or worse.

As of this morning, the Professor Watchlist website displayed a generic error message stating: “This Account has been suspended.”

Archives show the website was active as recently as May 9.

Right Wing Watch attempted to reach someone on the project at the phone number that was listed on the Professor Watchlist website but was unable to connect with the number listed, indicating that it may be disconnected.
