There are two options for new Inbox filtering in new GB
Basic Filtering
If you select Basic Filtering, you’ll see mostly messages from friends and people you may know (for example, friends of friends) in your Inbox. People who had the previous setting set to “friends of friends” or “everyone” will have Basic Filtering on.
Strict Filtering
If you select Strict Filtering, you’ll see mostly messages from friends in your Inbox. People who had the previous setting set to “friends” will have “Strict Filtering” on.
If you see a message from someone you don’t want to hear from in your Inbox, you can select “Move to Other” or “Report Spam” from the Actions menu. You can also block people that you don’t want to hear from on Facebook.
