Is there a way to un-fan a club?

where it says

프로필 | 벽 | 업데이트 | 사진 | Clubs | Favorites | 팬 | Messages

its clubs...click unsubscribe

당신 look on your list of clubs and click unsubscribe on the ones 당신 don't want.

Not sure, but if there isn't that would suck. In 페이스북 theres Anti 또는 I hate pages and groups, so I don't see why here there shouldn't.
