Someone just posted on my timeline where only my Friends can post. The post is abusive. I looked and the person is in my friends list! How can that be? I can’t find any history of when that person became my friend. The only answer I can come up with is that when my iPad was unlocked someone accessed Facebook and friended me then deleted the track from my activity log and also accessed my emails and deleted the email notification. I would be grateful to hear how else you think they may have done it. Thanks.
