This has been going on for a long time, I saw it happen so many times when I used to sit on towers daily when I played.

Admins would suddenly appear when our guild went to attack "insert certain guild here" and drag or unstick us. They would suddenly disappear if there were hackers at our tower. Admins would warn us for harassing certain people yet do nothing when we would report.

Admins will always play favorites and it will never stop.
