Even though it's a newsfeed, only friended people & news can post on it, so it's still mine in a sense. I just got tired of the two of them, particularly her, spam-bombing the page with worthless drivel. And it shows up on mine, shoving my stuff to the bottom immediately. And I mean as soon as I hit enter. Don't bogart the page!
I think you still don't understand, or you do and you don't care.
Facebook is a public page, much like HBT.
Say the entirety of the Facebook newsfeed is 1 thread. ANY post on ANYONE's page that you are friends with will show up.
Anyone can post anything they want, and it will show up in that thread, regardless of how badly you want people to not miss your post... it's eventually going to go to a new page, and it'll be "back there."
The same thing happens on Facebook. If you don't like seeing her stuff, hide her comments.
However, my Facebook feed is worlds different than yours... if you posted your book Ad to your page, it would be on the bottom of my feed in no time as well, because all of my friends are posting too.
Do you understand that part? Your newsfeed is unique to you, based on how many friends you have and what they are posting.
They are not posting DIRECTLY to the newsfeed, they are posting on their own page, just like you.
I don't think I can explain what is going on any clearer.
What you did was go to her comment that she posted ON HER PAGE (and, showed up on your newsfeed), and told her to "shaddup with the BS." LOLOL, I'm still laughing imagining that exchange and can see why people are telling you that was probably in poor form.
That would be like someone telling you to stop posting your book spam on your page.
