Hello Codeforces!
I have now created a brand-new frontend for the cheater database that has been circulating in your CF recent actions for the last 48 hours. So now, please do NOT DM me or Proof_by_QED or cry. Now, you can submit reports here
Just a reminder that reports:
MUST contain conclusive evidence (just linking their profile and saying "he cheated" is NOT enough) Cannot contain too many submissions (we are human after all, we don't have all the time in the world) MUST have usernames spelt correctly. Case sensitivity is not important.
Here it is: https://cf-cheater-database.vercel.app/
Note that the Chrome extension remains unchanged and still works.
UPDATE 26/06/2025
Hello Codeforces!
It's been amazing seeing you all contribute to this project — so thank you very much for doing so. I need to share some updates.
APPEALS — now, if you feel you have been wrongly labelled as a cheater, you can submit an appeal directly on the website. Therefore, do not spam the blog further, and use the website.
CHROME EXTENSION — some people have reported a bug with the chrome extension where it does not highlight all cheaters. This was a genuine coding mistake from me, due to which I have released a NEW VERSION of the chrome extension. Please redownload it from GitHub and reinstall if you downloaded the extension before today.
OUTAGES — some people reported outages — these are again the fault of the developers, and the issues have been fixed.
POLICY – Add ALL cheaters to the platform, no matter how they cheated. Submit concise reports with clear, conclusive evidence — full profiles will be ignored. If a report is declined, gather stronger proof before resubmitting; do not spam the same report multiple times. If you are submitting a report and see a skipped submission/contest, you can attach it, but the mere existence of a skipped contest does NOT constitute conclusive proof that the user is a cheater, especially because Codeforces marks all but the last AC submission as Skipped in Div 1 and 2 rounds.
Thank you again for all of the support, with your help, we are well past 1000 cheaters in the database and this number is quickly increasing.
