Should i lock it now?

How did I recover my account?

1. I logged into my account using the "forgot password" setting. Then, a recovery link was sent to the "yopmail account" which can be used to change the password of your account.
2. After changing the password of my account, I also changed my email address, and added a new security question for additional security.
3. Afterwards, I deleted all the forum's messages in the yopmail account so as to prevent the hacker from undoing my change password nor locking my account.
