The Reason Behind QueueForces
By Conqueror_of_Dominater69, 5 months ago, In English

Codeforces has long queue literally throughout the day now.
The main reason for this are some obvious bot accounts which are just submitting 1e18 solutions a day and ruining the experience for everyone else.
Here are a few of them :
1. imraquibe
2. SJCHSKY
3. drnbrhrdt
4. aftabroushad711
5. ScorpioDaggar

Just look at their submission graphs.

Its so blatantly obvious that these are bot accounts which are just here to ruin the website, and there are hundreds of them.
Kindly look into this MikeMirzayanov and Vladosiya.
I'm sure people can put in a bunch of fixes for this in the comments like limiting submissions to 5 or something for unrated users.

Maybe can limit users to a certain maximum number of submissions per day, one which no real person will achieve but will stop bots from flooding the queues.

    Maybe a submission limit based on rating(limitations being based on rating is nothing new to codeforces, report button is locked behind candidate master for example)

    So unrated people get like 100 submissions a day, it increases until you reach specialist or something(subject to change) and then stays unlimited going forward

      i dont think rating is the way to go here, some people just dont participate in contests for reasons such as time zone. i understand what you mean but if such idea would be implemented i think it'd rather be through a different metric

    20 is a good number

      Not at all. if you solve 5 problems in that day, you have 4 submissions per problem. Which is way too small to do anything. To put in comparison, OI style contests(where there is generally 3 problem) have 50 submissions per problem limitation. And people still manage to get 30 or so submissions while genuinely solving the problem

    But bots can easily circumvent the limitation by using more accounts.

We can literally put an IQ test instead of a captcha.
