Queueforces again?
By zac2010, history, 11 months ago, In English

Oh my god, Codeforces is once again jammed by a massive number of new accounts without ratings, turning into "Queueforces". This might be a problem.

Most of them are unrated and submit solutions too frequently. I suspect they’re bots.

every botted submission has a UUID at the end. 347605306 347605303 347605385. wouldn't be surprised if this is some training for LLMs and the UUID is being used for tracking.

    And got WA on test 1.Seemed that the examples weren't being used as the very first testcases are mostly examples that are given in the discription.Also,obvious AI style for coding.

Every time I visit Codeforces I get slapped with a Cloudflare captcha, but these bots can submit whatever they want whenever they want

It is crucial to add limitation of submission frequency or AI detection. The headquarters may need to control the situation by punishing (or banning) unrated (or rated) accounts when they "abolish" the judging process.

guys it's true that 15 hours ago the queue is long,
but the newest one I think the judge died instead of long queue.

I also checked problemset status and found several bot-like accounts flooding the queue. And I observed same pattern across : - Submission every 1-3 mins for hours with no breaks - Random compiler - No retries even if solution is not accepted
This behavior looks automated and could be one of the reasons the queue keeps getting jammed.

What is happening? I submitted my first problem of the day at 8:52 AM still it is showing judging? Is their any testing going through codeforces?

I think CF can temporary disable submissions from some specific problems which are seemed to be spam. I saw in status page has many submissions for problem 724G. In the future, CF can do the same thing when count the number of submissions is high (for problems are not in contest). I guess this may help to fix the "in queue"

    thought that problem is just chosen randomly.maybe someone wanted to attack CF?thus banning one problem is of no use.as some of the bot accounts even mimick those of rated users,i thought that might be an organised abuse/attack?

      At least it may help us at the moment. If anyone pick problems randomly and attack, I think it's impossible to prevent

Codeforces should ban unrated first time submission in contests

Captcha is easily solved by bots instead, we should use internet memes. for example, we ask the new account:

which number is special? 67 or 71 ?
