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.
Strongly support. Codeforces should have a private anti-cheat report channel. It should be more formal than Mike's DM so everyone will use it. Blogs that exposes cheaters like what we have currently should be marked as "no reasonable content".
