How to stop FaceBook notifications from unknown people?

[journey00]

I do not want to to be notified when someone I don't know or their friends posts something on my friends wall or makes a comment about their pics or whatever. I only want to see notifications that are addressed to me.

There is no way for the system to know which comments pertain to you and which don't. If you have commented on it then you'll receive notifications about it

Try this...Click on the “Notifications” button at the bottom right corner
Click on “See All.” On the right, you’ll see a long list of every application that sends you notifications, and you can turn them off by unchecking them.
Facebook’s own applications, although they may not be useful to you, such as feed comments, are also on the list.!
