Hello, I am facing a strange problem with my account.

Every time I log in, after some time I get logged out automatically and I see this message:

"Recently, your account was used to crawl. Please change your password to prevent your account from being used for unauthorized activities."

I already changed my password several times, but the problem keeps happening. I do not use any scripts, bots, or unauthorized tools. I only use Codeforces normally for practice and contests.

Can you please check my account and advise me how to solve this issue?

Thank you in advance.
