Hello, I am Basilhijaz. I participated in lots of Codeforces rounds and the last one I did was Educational Codeforces Round 155 (Rated for Div. 2). Unfortunately, I was trying to login to my account today and got the message "User is disabled by administrators". I checked my email and it looks like I was accused of cheating in that specific round. Apparently my Submission on Problem B 224888371 is so close to LetsPractice's Submission 224901176.

This problem we both got accused of copying from each other is B in an Educational round which means solutions can get actually really close and if you notice the solutions are so short which increases the probability of matching.

Previous Accuses of Cheating Attempts (Problem, My Submission, Similar Submission/s)(problem classification):

• (1462D - Прибавления в соседей, 101301240, 101299306) (D div3).

• (1670A - Профессор Слим, 156079546, 156080306) (A div2).

• (1695C - Нулевой путь, 161080032, 161069277, 161070788) (C div2).

• (1778B - Запрещённая перестановка, 191560615, 191583829) (B div2).

Observations:

• Most of the problems I got accused of cheating are <= *1400.

• The solutions are quite short and easy to come up with.

• All cheating attempts are with random/different people having no connections with.

• I never publish my code online during contests or use ideone.com or any similar websites.

Credibility:

• ICPC finalist for the upcoming ICPC 2022-2023.

• IOI Participant twice (2019 and 2020).

• Joined Codeforces more than 5 years ago.

• Did 231 contests on Codeforces.

• Solved Over 2000 problems on Codeforces.

Actions I previously took for previous accusations:

• Commented after a round with this comment.

• Sent a message to MikeMirzayanov which I got no reply on.

Mike replied to my comment: "_lightning rarely strikes the same point twice_". Well, looks like it hit five times the same place. I am sad to see all of this happening right before ICPC and preventing me from practicing and doing regular contests.

Regardless of the effort done to build the cheating system, I think the algorithm needs quite improving.

After writing comments and messages and not seeing any action happening and getting almost every time my solutions to get skipped and me losing ranking with no action, I hope this time it's different.
