For div 4 my rank was 2986... and for today's div 2 it was 2861, but still the delta is almost same. How can bringing almost the same rank in div 4 and div 2 within a month give you almost same delta?

Hello Codeforces community, Today just after the contest, i am continuously getting a message saying " Recently, your account was used to crawl. Please change your password to prevent your account from being used for unauthorized activities.". I have changed my password but the message is still there even after relogin. Even in the hacking phase I tried to view other's solutions but I am being logged out. Can anyone please help me through this? Tagging MikeMirzayanov just so that the issue is highlighted.
