Maybe because you were unbanned prematurely by another admin who did not consult the admin that banned you. Asking to be unbanned by some other admin and then having that admin override the ban (unless it is ZER0 or Jigsaw) will put a big target on your head for more bannage. Also, the one that has been unbanning you may get in trouble also.

I'm just thinking of the time where you were banned for a week after consistent warnings not to break the planks on humans on ze_jurassicpark and manage to be back like a couple days later.
