I wish more teachers and academics would do this, because I"m seeing too many cases of "That one student I pegged as not so bright because my class is in the morning and they're a night person, has just turned in competent work. They've gotta be using ChatGPT, time to report them for plagurism. So glad that we expell more cheaters than ever!" and similar stories.

Even heard of a guy who proved he wasn't cheating, but was still reported anyway simply because the teacher didn't want to look "foolish" for making the accusation in the first place.
