If you are having such a high listing of buddies as well as joined some variety of teams than you could have some problem with the notifications. I know this due to the fact that a lot of my friends are addicted to playing those Facebook games and also I obtained a lot of notifications of invites and requests.
Not taking way too much time with my own problem I would love to share what I am doing to stop those notifications.
Turn Off Notifications Facebook
STEPS
1. Most likely to your Facebook account.
2. Click on the "Notification". Where you obtain all your alerts.
3. You can see establishing alternative there. Select it.
4. Now select when you want notification.
5. Select your Alternative and minimize your list of notifications.
Those are the actions that you have to do. Well with this technique you can not quit all notice but it will undoubtedly lower the number of the notices. In my instance it minimized to the 40-50%. So it is worth to attempt to stop to some pointless apps as well as video game alerts.
