I know there are some other posts about this. I list some bots here.(I'm also wondering why some account were not banned before)

Bots with UUID in the code.

(Bad English, so I used AI.)

Bots appear to be from the same LLM.

They have random names(the name length is always 10), an empty first line in their code, and attempt problems sequentially by contest ID (e.g., one tried IDs 835–909).

Since these accounts are registered and abandoned within hours, I think additional registration verification is needed.

Smarter bots, only can be known with AI comments.

Maybe bots, but "Recently, your account was used to crawl." so I can't look submission.

Each time I update this post, I found new bot accounts. =(

Maybe I should @MikeMirzayanov?
