Twitter Removes Tweets from Student Criticizing Proctoring Company

A series of tweets by one Miami University student that were critical of a proctoring software company have been hidden by Twitter after the company filed a copyright takedown notice. Erik Johnson, a student who works as a security researcher on the side, posted a lengthy tweet thread in early September about Proctorio, an Arizona-based software company that several U.S. schools — including his own — use to monitor students who are taking their exams remotely.
