Hi, I recently received a warning about suspicious activity on my account. Details as follows: "Recently, your account was used to crawl. Please change your password to prevent your account from being used for unauthorized activities."

Furthermore, I realized that after Hello 2026, Codeforces automatically logs me out whenever I try to read any submissions (from the scoreboard, or even my own submissions status). Should it be a bug, or am I banned from reading submissions?
