I looked through all my screenshots from around the time you were banned and was unable to find the screenshot with your grief. You are right in that the my sibling/friend did it excuse is common, and it's also not accepted as a valid excuse. You are in charge of your account and anything that happens on your account is your responsibility. Since I'm unable to find the screenshots and you will have to go through the tutorial anyway, I will unban you.
