The choppy language is the biggest trigger for me. Examples:

* "With Fraud Defense, there was no process to respond to. The product launched. The requirements page went live."

* "That is not a technical limitation waiting to be engineered around. It is the mechanism."

* "The defeat is mechanical. Bot operators point a camera at a screen, a trivial automation with off-the-shelf hardware."

I could be wrong, of course. Maybe humans are starting to write like LLM's, or maybe it's just confirmation bias on my part.
