We are aware of this submission. The high scores are a result of prompt injection attacks, instead of data leakage.
We are actively discussing with the Meta team on how to eliminate such attempts, either via added clarifications to the rules and/or technical methods However, the organizing team reserves the right to disqualify submissions that are clearly trying to exploit a loophole, or are not aligned with the spirit of the competition, and we will check all code before final winner announcements to invalidate all such attempts.
