Professors around the country are expressing concern that their recorded online lectures may be shared by students with conservative media outlets.

According to a report by Campus Reform, professors at universities and colleges around the country are worried that their recorded online courses will be shared by “right-wing sites.” Many professors expressed concern that their classroom lectures on controversial issues like “immigration” would be picked up by conservative news outlets.

In a tweet thread, professors at different universities voiced their concerns to one another. One user in the thread argued that conservative outlets have a “history of making misleading edits to remove context” and then sharing those videos “get professors in trouble.”

“If you are recording a lecture on anything controversial, be prepared for right wing sites to ask students to share it,” Texas Christian University Associate Professor of Political Science Emily Farris wrote in a tweet.

Another professor, Trinity College Associate Professor of Political Science Isaac Kamola, accused conservative outlets like Campus Reform of trying to “delegitimize” far-left professors.

“If Campus Reform harasses you or someone you know, the best response is to ‘follow the money.’ Campus Reform receives $1.4 million from the Leadership Institute, a Koch-funded organization designed to delegitimize academics they consider too left. They are not a new [sic] source,” Kamola wrote in the thread.
