As a person that has -28 contribution, I'd really want to contribute something to our platform. So, these are some people that I strongly believe that are using tools in the latest round:

tanguyenhaonam — in submission 380758890 and 380754042, they have significant different code format

vid1606 — AI-alike variables in all submissions.

Darshil_Prajapati13 — really suspicious contest timing, spending 2-3 minutes on every problem???

Dharaneswar-Reddy — AI-alike variables, comments in A and pretty fast contest timing.

caramel29 — AI comments in B and E, also spend 1 minute on B,C,D (bruh)

Note that everything above MY opinion, so if you don't agree with my opinions, you can comment in! Thank you!

Also shout out to DuyMinh3005 for helping me find these guys!
