How come we don't get any notification at all when we lose a ファン on this site?

Each time I get myself a new fan, there's always a message waiting for me in my mailbox. I opted out of gettin' Eメール notifications to save my personal mail from being flooded with all those ファンポップ notifications. But, what about losing a fan? I just ロスト a fan, and a friend, too, and I never get a single note from this site! I don't get it! Is it just me, または is it something that happens to everyone else on this site? I'm still new on this site, so I don't know how this site works. Does anybody know もっと見る about it? Thanks.
