There's no incentive to cheat — you'll get caught sooner and later. You'll create a new account, get caught again, and then get IP banned.

The Codeforces cheating detecting system is not foolproof — one can simply get all the codes from Open AI, alter some lines and change some spacing, then wait a reasonable time before submitting it. They would still gain a lot of rating, as they would still get close to first place.

But this shouldn't be a concern, as the entire Codeforces community is built upon integrity.

But somehow, this is a concern. For some reason, cheaters exist and are thriving in Codeforces. This should not happen.

Honestly, normal bans are not OK in this scenario. If a cheater cheats, DON'T just disable their account — they will just create another one. Codeforces will have to IP ban them.

Please comment suggestions. This problem is getting worse and worse. In the last few contests, more than 4% of the top 2000 participants were cheaters. This is not okay.

A response to "its okay just let them cheat": Sorry, but I strongly disagree. Allowing people to cheat without a serious consequence is a huge issue. Cheaters will just keep farming rating, while coders who don't cheat won't gain as much rating. This will make the coders who didn't cheat want to cheat as they see that they won't be punished.
