I have found these cheaters (there might be more) in Codeforces Round 965 (Div. 2):

Problem 1998C - Perform Operations to Maximize Score:

Way.To.Cp.01 : 275578036

tdkhai : 275612866

Thalleous : 275630857

quangthangg : 275606510

Problem 1998D - Determine Winning Islands in Race:

Way.To.Cp.01 : 275600882

tdkhai : 275621859

quangthangg : 275617803

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
