When was this taken? I saw something about nadgeynoodles, he was perma-banned for griefing and he comes back as alts to try and steal/grief me. Hasn't happened for a while, he came on as nadgekins72 ages ago.
I think I can explain this. Around a year ago, Mojang introduced "Mojang" accounts in addition to plain "Minecraft" accounts. Players were given the option to migrate to a Mojang account. However, there was a bug in the login authentication servers that let anyone log into a Mojang account without a password. That's probably what happened here.
It's obvious. Notch heard about shade crest, thought it was a good server, and decided to check it out. Quite simple really.
