If I share a photo album on Facebook with "custom audience" then will their mutual friends will be able to see those photos?
I want to upload family albums and I want only selected people to see.
If a person in my custom audience comments on a post, can their friends (or our mutual friends) then see the post? (People who aren't in the custom audience.)
Best Answer
No, other people will not be able to see that post.
