Current Leaderboard Potentially Affected by Duplicate Accounts
18 May 2026, 22:08 · 4

I would like to raise a concern regarding the current leaderboard activity, as some patterns appear highly suspicious and may suggest the use of duplicate or unfairly coordinated accounts.

For example, there are cases where a participant joined the competition less than an hour ago and already has around 10 high-grade submissions. Realistically, it is difficult to understand how someone could, within such a short period of time:

  • Join the competition,
  • Read and fully understand the instructions,
  • Set up their environment,
  • Learn how the platform and submission process work,
  • Develop or adapt a working solution,
  • And then produce multiple strong submissions almost immediately.

Even with the assistance of AI tools, the speed and quality progression in these cases does not seem natural and raises fairness concerns for genuine participants who are investing significant time and effort into the competition.

Thank you for your time and for maintaining a fair competition environment.

What is the probability that two submissions get identical scores for the |MBE| and RMSE parts?

That is strange! Almost 0, I will say. Thank you raising this up.
