I have found these cheaters (there might be more) in Codeforces Round 965 (Div. 2):
Problem 1998C - Perform Operations to Maximize Score:
Problem 1998D - Determine Winning Islands in Race:
Looking at the time and performance, it seems like Way.To.Cp.01 is the leaker.
MikeMirzayanov please take action as these behaviors are a disgrace to the Codeforces community.
Apologize to your parents rn! :333
