I have to say sorry to you because my English is quite bad.

Codeforces community has happened something unpleasent recently,and I have some doubts.

As everyone knows,goodbye2023 is hard to be called a good contest.It has three problems which have appeared elsewhere before.More absurdly,you secretly rated it,even without a "You are wrong,here is why".

As everyone know,Kangyang Zhou is one of the top coders in today's world.And he just used two accounts to take part in different contests.He never do something cheating by his two accounts.And I have enough reasons to believe he will also get good grades if he has only one account.So,in my eyes,what he do can not disrupting community order.

If you insist on saying "Two accounts have bad effect and it violates Codeforces rules",I think I should talk to you.

Firstly,Codeforces rules is not immutably and they mustn't be immutably.They must follow the paces of times.Having multiple accounts has been a common things nowadays.Furthermore,If you insists on the policy of using a single account,why don't you ban all illegal accounts?You just want to ban some illegal accounts with high rating,isn't it rating discrimination?You think users with lower rating are unworthy of your attention?Of course,you don't have the ability to ban all illegal accounts.Since you can't eliminate the unfair phenomena,you shouldn't just ban some of illegal accounts.

Secondly,since you attach importance to the fairness of community,why you still rated goodbye2023?Problem H1 and H2 could be easily on oeis.org and I think most of solvers of the two problems solve them by using oeis.Is it your original intention to test participants' oeis ability?Of course not.So why do you stick to rated it?Your action seriously effected Codeforces community's fairness.

Why do you not ban goodbye2023 but ban zh0ukangyang?
