Good tip. I checked it but "close friends" is empty. But you may be right. Even though i don't interact on Facebook; i only check what videos/pics/news they shared and click the ones that i am interested in. (not even 'like' them) But as you said, Facebook is probably tracking my 'clicked news/pics' and show those friends' activities. I will monitor it for some time. Thank you all for the tips. Have a great weekend.
