I would like to know when I can freely choose whether to join the hack room.
Twelve hours ago, system sent me a message saying that my 2030D code overlaps with that of more than ten other people.
But I have never leaked my code on any platform, nor have I colluded with others in competitions. I also cannot accept a rating that doesn't match my ability, as it would lead to incorrect assessments of my personal skills and my team's strength in offline competitions. After receiving the message, I went online to seek advice on what to do, and someone told me about the hack room.

If someone solves the problem, locks it, and enters the hack room to view and leak others' code...

This is practically impossible to guard against, and I have no idea how to prove my innocence.
So, I don't want to prove my innocence anymore. I just hope that during the competition, no one can see my code.
So when will I be able to freely choose whether to join the hack room?

Hmm, a comment informed me that I could check the room information. So... https://codeforces.me/contest/2030/room/186
