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", "I don't want to see you on my page anymore" or anything close to those that's not really me. That's the hacker.
Write all of this down in your journal too!!
