She finally did it. After almost 24 hours the hacker "m a l c o n t e n t" hacked my friend Mahoux, and I, like him the first time, watched it happen.
This time however, she did change things on his account.
She changed his status to "Big Brother is Watching (d)" like with my experience and also uploaded the same photo that's on her account to his. Next, she deleted his other artbook and YouTube playlist, replacing the latter with a quite creepy series of videos. Finally, she changed his artbook warning people about her to a full screen of that photo with the following in red TWICE:
BIG BROTHER IS WATCHING
THIS IS YOUR FIRST WARNING"
He hasn't came online yet, but I have these messages (in the gallery)
