Sometimes they way some people share links to their blog posts on their personal Facebook timeline make me believe they are either fake profiles or their account have been hacked. When you share too many blog posts on your Facebook timeline, some of your friends will learn to ignore you, even when you post something important. Some will even find a way to silently unfriend or unfollow you. Yes, some friends are that unfaithful.
If you must share on Facebook, as I have earlier suggested, create a Facebook page or group. Sharing on your timeline should not exceed 3 links to your blog posts per day. And doing that daily is even excessive. You should really avoid it.
