I don't know. Try it and see. Let us know. See if anda can. anda could always RE-fan it. :)
She is right, I do not know if anda can, but if so, anda would no longer receive update in that club. The club remains there, but anda would not be listed any longer under fans. If anda wish to leave any club, that is your choice, so if it will let you~ anda can. If anda wish to a remove an entire club anda made then that is another story & takes reporting the club & explaining.
It's the same as if anda unfan a normal club, anda don't get the update and it's not in your club list. But, anda can still ubah the club. Like I unfanned a few of my own clubs, but I can still change the motto, banner, and icon.
