Oh, and there are a couple of ways to unfollow.
When someone posts something you don’t like, you go to the top right of their post and hover the cursor just under the thin line that deparates posts. A little arrow will appear, click on it. You will be given options. You can delete the post, or unfollow the poster, which deletes the post and stops any others from them from showing on your page.
You can also go to the persons page and look for the button that says, “following”. Click on that and you will get the “unfollow” option.
You don’t want to deal with following hundreds or thousands of people, even if some of them post good stuff. The purpose of the page is to push people to FR, not to allow spam from idiots. At least, that’s my take.
Unless you are administering a page, nothing you do will keep others from seeing spam or blogs or shoe salesmen.
The question here, as I see it, is one posed at the admin level.
Certainly as a user you can hide things from yourself.
Really all that does is make you ignorant of some of the
goings-on.
Blinding yourself to the bad things simply lets the bad things go un-opposed by you, since you can’t see them.
