Is Something Wrong With Facebook Notifications? Or It's Just Me?

For about a month i've noticed that Facebook iOS app is sending me a lot of notifications about everything. Some friends' status updates, some friends' photo shares, etc. Lots of irrelevant notifications. It's not some "specific friends"; randomly.

It bothered me a lot and i turned all the notifications off of Facebook in the Notification Center. It didn't solve the issue. Then i went to the settings of iPhone for Facebook app and turned off all the notifications. Now i'm relieved.

But when i go to Facebook through the browser on my desktop PC, i noticed that it wasn't the iOS app, but it's Facebook itself. Whenever i visit the page there are new notifications; totally irrelevant and that weren't coming before.

I checked the Account Settings->Notifications. All the notifications that i don't want are disabled. Only "friend request", "tag photo of me", "message" are active. But i am receiving the notifications from other ones as well. And a lot... And this is really annoying.

Anybody who notice that kind of anomaly in Faccebook notifications? And any solution about this thing?

Many thanks. Serdar
