The last rollback from Goodbye 2025 Codeforces round starkly reveals a crisis of fairness. My rank jumped from 3141 to 3017, not because my code suddenly optimized itself, but because a large number of cheaters were skipped. It means 124 fraudulent participants were skipped from the top 3000. This indicates that approximately 4.13% of top contestants relied on AI to generate solutions.

Moreover, there must be more cheaters who have not been detected and still steal top rankings and high ratings.

Such behavior does not merely exploit a loophole—it fundamentally ruins the spirit of competitive programming. Platforms like Codeforces are designed to test problem-solving under pressure, creativity, and the rigorous application of algorithms. When code is mass-produced by AI rather than cultivated through careful thought, contestants cheat not only the system but also themselves, missing the growth that comes from struggle and debugging.

Worse, this trend erodes trust across the community. Honest participants see their efforts devalued, while the scoreboard becomes a distorted reflection of true skill. If contests turn into battles of who can best manipulate AI tools, rather than who can think critically and adapt, they lose their purpose as arenas for human intellectual growth.

I urge Codeforces and similar platforms to strengthen plagiarism detection and adopt proactive measures against AI misuse. More importantly, we call on every participant to uphold integrity—because the true reward of competitive programming lies not in a temporary rating, but in the authentic, hard-won brilliance of human thought.

This is no longer just a loophole — it is an existential threat to the credibility of our community. Every skipped cheater represents a stolen moment of genuine effort, a legitimate ranking that was unfairly denied. We cannot remain silent while the arena we cherish is corrupted by AI posing as intellect.

We must act now: first, advocate for stricter, real-time code provenance analysis that detects AI-generated patterns beyond simple plagiarism. Second, as a community, we must cultivate a culture of collective vigilance—where reporting suspicious activity is seen as an act of honor.

The scoreboard should reflect human minds at their most resilient, not the most efficient cheating methods. If we fail to defend this principle, we risk losing the very soul of competitive programming.
