Two days after the large-scale cheating incident that occurred in goodbye2020, Mike and the codeforces team still did not make an official response to the incident, which made me (maybe us) very disappointed. Maybe there is not enough evidence to prove that the cheaters did cheat, and it is difficult to change the result of that contest. But at least, the codeforces official should have a statement on how to prevent similar incidents from occurring in the future, and corresponding measures, etc. But I did not see these. I love codeforces, but codeforces disappointed me this time.
