Hi @johnpayne0, I believe the main reason they do this is to sell medals after winning. They create multiple secondary accounts, wait for the competition to end, and then sell the accounts with the medals.

\nI didn't read the whole details of this competitions, but two teams with same code may not be recognized as \"cheating\", that's because anyone may use the shared code in discussion board, and of course you can't win a medal by using the public code. However, if the code is not public acquired, and 2 teams submit them \"in coincidence\", would it be treated as cheating?

I've also seen certain kinds of medal selling services, saying that some kaggle grandmasters will help you code and get the medal. You need to pay lots of money for it. Actually, there must be many kinds of cheating in the competitions.

Since they don't have exactly the same score, someone may have shared a magic feature privately. Such competitions usually have magic features (or a magic architecture)

their score doesn't seem to be high enough to have magic feature/architecture. i think u can easily achieve that score with default features and mlp with online learning.

Sure, but regardless of their score being low or high, ideally every potentially misconducting account(s)/person(s) should be reported to Kaggle so appropriate actions may be taken.

It gives them a leg up by being able to test a bunch of models in parallel and choose the one that performs the best. Skill issue tbh

Hi @johnpayne0, I believe the main reason they do this is to sell medals after winning. They create multiple secondary accounts, wait for the competition to end, and then sell the accounts with the medals.

Currently, similar situations exist in other competitions as well. For example, https://www.kaggle.com/competitions/llm-detect-ai-generated-text/discussion/469636#2612672,and https://www.kaggle.com/competitions/eedi-mining-misconceptions-in-mathematics/discussion/551276
