There are platforms now using temporary email addresses to register bots.

The pattern of these bots is that they are all unrated and the username is a random number or letter of length 10, and they will submit several times per minute.

I suggest Mike send an email every 200 submissions to all unrated accounts' email to verify this type of bot.

Here are some examples:

0n9nm0y6ho submitted more than 60 submissions in just 20 mintues. tzqymu69i6 50 summissions in half an hour. zunbgg8w3g also 60 submissions in half an hour.

I want to know why they are all using Python and have the following code content:

if __name__ == "__main__":
    main()

Are they training AI?

These bots seriously affect normal user code submission.

MikeMirzayanov, please ban them.
