I wouldn’t have tagged the ban as griefing if it wasn’t. However, since it was so long ago and there are no logs on it any more, I suppose it’s kind of forgotten in the servers’ eyes (and in mine). So you’re unbanned, just know we’ll be keeping a close eye.
We consider an AFK machine to be a very serious infraction that should not be taken lightly. Therefore, I’ve decided not to unban you because you were intentionally breaking our ranking system, which is clearly stated as an offense in the rules. As for you not having read the rules, you should have read closer.
You claim that you “learned your lesson” but nothing suggests to me that you did. You knew that griefing was against the rules – obviously – and the way you griefed couldn’t be considered unintentional: it was a deliberate attempt to rile someone up and cause harm to their belongings/property (evidenced by the scale of the griefing and the hella mature sign saying “LOLOLOLOL”…). You’ll remain banned.
