That and potentially asking it specifically to not follow certain patterns. I also wonder if the false positive rate in a college/school setting will be higher. Because to me, it seems that these models are often trained on college papers.

Because I see a lot of the patterns you already see on those. Specifically, paragraphs that start with conjunctive adverbs and phrases. Things like; however, furthermore, moreover, in summary, in conclusion, etc.

Besides, smart students that are not utterly lazy will be able to work around it anyway. They'll let chatGPT (or whatever LLM) turn out an entire paper for the contents, then rewrite it themselves.

So a tool like this will only catch the most obvious cases. Meaning that in the end it only battles a symptom by effectively sweeping it under the carpet.

Am I right that "bad actors" here refers to the actual paying users, i.e. us and our children?
