There has recently been a very serious issue with compromised admin accounts due to easy to guess passwords. In the last 2 days, 4 admins have lost their sysop status because their password was guessed.
Please ensure that your password cannot be guessed, do not use words in a dictionary, or names, or hobbies, or any personal information as a password. The best password should be random. People are actively trying to guess your password and if they do you will be desysoped when they usurp your account.
