"The hacker has indeed been confirmed. I saw a journal that one of my friend posted. The hacker apparently hacked into a group previously. So this indeed is real. well, don't I feel stupid.
This guy is known to try and get you banned by commenting crude things to others. Namely the watcher the person watches. Here's the message going around for this hacker:
"Rumor has it there's a hacker on dA, hacking people and blocking our friends to make them block us! You'll then be banned from dA
Write the same warning in your journal to protect not only yourself but everyone! Here's another warning: If I'm being a jerk, saying stuff like "Shut up," "Get lost", or "I don't want to see you on my page anymore", that's not really me. That's the hacker.
Write all of this down in your journal too."
So keep an eye out for this guy. I also heard he finds you through journals. You see the check box that says Journal Portal at the bottom? Uncheck that, he cannot find you really. Just until it bows over lol. "
I realize this is a chain but i'd prefer to be safe. Sorry for the journal spam.
