I and my student lily participated in this completion about one month ago and achieved 0.597 score about 5 days ago. RunningZ contacted me by WeChat on January 21, 2023, and wanted to join our team. I knew him in KDD CUP 2020, which is also a recommendation system competition (KDD Cup 2020 Challenges for Modern E-Commerce Platform: Debiasing). He was a team leader and ranked 3rd finally. I was another team leader and ranked 6th. I think we could get a better score after he joins our team, and invited him and shared him with our codes.
\nOn January 24, he submitted an ensemble submission and achieved an excellent score (0.601). I was shocked by the ensemble, and he just said he did voting, weighting and stacking based on our previous submissions and our codes. Then, he let me make him as leader and contacted other competitors to merge teams. Finally, Konstantin Gavrilchik and Ilya los agreed to join our team. Konstantin Gavrilchik created a Slack channel to share solutions and discuss problems.
\nOn January 25, RunningZ contacted me by WeChat and let me share our solution and let me say our best single model achieved 0.599 score, which is something weird. I briefly introduced our solution and claimed that our best single model is 0.597 and the ensemble solution by RunningZ can achieve 0.603. However, I don’t know exactly how he did it. After that, I asked him by WeChat and wanted him to provide the ensemble code with me, but he said his code was messy and let me continue to give him results of single models. Actually, although I have achieved top ranks in several recommendation system competitions, I haven’t tried the ensemble method to vote on multiple submissions, which may be useful to improve performance.
\nAfter a few hours, I checked my email and found someone told me I should focus on the ensemble pipeline by RunningZ, and I talked to RunningZ by WeChat. He promised to share his code with team members in the evening. The ensemble performance also surprises Konstantin Gavrilchik and Ilya los. However, RunningZ has not reproduced the submission and provided his codes until now. And he was inconsistent in his words in the chat history of WeChat and Slack.
\nWe wish Kaggle could handle this matter. And a suggestion (https://www.kaggle.com/competitions/otto-recommender-system/discussion/380783#2115469) may be useful to team up in Kaggle competitions. Code verification is also necessary for gold solutions, and the solutions should be posted on github. My students and I always did this, such as CIKM AnalytiCup 2019 (https://github.com/ChuanyuXue/CIKM-2019-AnalytiCup), KDD CUP 2020 (https://github.com/ChuanyuXue/KDDCUP-2020) and WSDM CUP 2022 (https://github.com/hansu1017/WSDM-CUP-2022-Retention-Score-Prediction). Eventually, I am very sorry to have involved Konstantin Gavrilchik and Ilya los in this accident.

Thank you for the raising this issue. The next questions are
\nI was contacted by RunningZ and a other top gold solution guy separately currently in this competition, even before they submitted, just a few days back. They must be really pros to contact for team up even before making a sub. I am happy I did not team up.
\nAlso I really appreciate Bruce for openly raising the serious issue, even though it affects your team's chances in this competition.
\nA jump from calculation 0.597 to 0.603 is fantastic, that of a superhuman, unless you already have some subs from the 0.6+ range already with you, question is from where did he get it ?

\nPretty sure there are much more cheaters, guys, please report if you found any suspicious activities!
\nWell done Bruce!
Besides the sad story for you, this is great to read. I hope Kaggle will enforce you suggestion that every gold medal code should be made public. I didn't do it consistently in the past but I would if this is the rule from now.
\nI once was disqualified because we (Giba and I) teamed we someone who cheated (he used 3 accounts). We were in gold in private lB before being removed. I can understand how you might feel.

\nActually, I don't need a medal to prove myself. One main reason I participated in this competition is to prepare materials for the next semester's course. And now the first lesson will be honesty and rules.
\nAdditionally, I wish kaggle could give Konstantin Gavrilchik and Ilya losthe the medals they deserve.
@bruceqdu , You are the pride of kagglers ✔️

\nSimple solution: Do not add an unknown teammate if you do not accept the worst-case scenario.
Btw, I read many were shocked, this is normal human behavior.
\nOn the contrary, having high-grade ethics is the abnormal.
