The great wall of india  Hi. See todays rounds ([contest:2162]) standings, front two pages, and 700-800 These are clearly bot accounts so my question is the following: what exactly does cloudflare contribute???? it blocks normal users, but when there's an actual botnet on the loose, they're all let through? Of course, naturally all these bots are utilizing LLM to solve as well, so please consider filtering for unrated that solved either a b c d f g, or a c d f g (because their b fst/hacked LOL), for an immediate purge (not including the normal plagiarism check) this nonnegligibly affects participants in the top 2000 of the contest, more than any other recent case of cheating note, f is much more difficult than e from my experience, so not being able to solve e, but solving f is a clear sign of LLM. I ...

Hello your computer has virus: A case analysis how the current issues on CF and how to solve them Now I know what you're thinking... "oh no. hes being racist again" however, if you would so kindly look at any recent standings, especially ones which favour the timezone of indians... (like the last div1,div2 combined round...), you would notice quite the coincidence. And if you think, oh well Codeforces is fucked... you would be wrong Codeforces gets the short end of it, just look at meta hacker cup round 3, and compare it to any other year. Now is calling out Indians racist? Without valid reasoning that they are the supermajority causing issues, yes. However, I believe I have valid enough reasoning. If the pure statistics don't convince you that we must target punishments towards India/bangladesh/pakistan?/basically that geographic region, then why not use logic instead? Why do these people want to cheat? Well I've asked a few who obviously, I will keep anonymous. Simply put, its peer pressure. Somehow, most likely due to government corruption and other political things...

Cloudflare Turnstile Integration Bug Since the end of [contest:2227], I've been trying to upload a solution just for the sake of solving the problem, but there's an empty area where the Cloudflare "not a bot" verification widget is supposed to appear, on the right-hand side on the problem statement, in the submission box where one can upload a file containing the solution code. Because the widget was not loading I couldn't use that submission box, so I tracked down the problem and discovered that there seems to be a bug in Codeforces' integration of Cloudflare Turnstile in that part of the site, though I'm not sure exactly why or how it happens. [cut] I have tested this on vanilla Google Chrome, Firefox, Vivaldi, Ungoogled Chromium, and Helium. For that reason I am confident that the issue is coming from the website itself.  Here are the details: ~~~~~ // the exact error varies, but it's the same general error that I've managed to reproduced ...
