If you realize setters took some interesting measure to identify AI code, just be glad they are going after cheaters and move on with your day. Posting / commenting about such measures just enables cheaters to realize them and be more careful next time, so we continue on this cat-and-mouse game forever.
If you think you have relevant new information, consider private-messaging setters instead of making a public blog post about it. As much as I love when cheaters get exposed, revealing how they got caught doesn't help the community in the long run.
