1. Never, ever comment in blog posts unless using a spare account. This puts you at risk for being hacked as hackers know your username and can easily try to crack your password.
2. Use a secret question instead of the "animal food" question set to recover your password. If it's your favorite food, set the answer as something random like your email address.
3. You can share you username on the wiki but NEVER share personal information, even if it is your favorite food.
4. Don't fall for any tricks like "I can help get you this item if you give me your password". This is a total scam.
5. Don't accept friend requests. This sounds silly, but to be safe, only friend people you see on the wiki for KK.
Please stay safe!
