I am sorry to bother you, my account has recently had some problems. It was stolen by someone else I didn't know and changed my password and email address. I don't know if I leaked my password, or just hacked by someone else. In short, I can't change my password and email address. I can use it temporarily because my account has not been logged out. I am afraid that he will take my account to do something unethical, such as stealing data from the gym, or deliberately deleting something I have now. I know that if this article is seen by him, it may bring more tragic things, but I can only pray that such things will not happen. I know his email, and I also contacted him through QQ, but I have never received a reply.
I also tried to contact MikeMirzayanov and asked him to change the email address and password for me. I have not received a reply yet. In addition, I want Codeforces to send email confirmations when modifying email addresses, which is more secure.
Finally, if you have recently seen me posting some weird comments, please let me know, my email address is: firstname.lastname@example.org, thank you!
