Windows 10: Contact and Unsubscribe Features

Hello,
I think I need to change one of my settings because on some sites that I visit, these features do not work. I use yahoo as my isp and am mostly pleased with it. I need some direction as what to check. The only hint I can give is that the features are greyed out.

Unsubscribe friend's Facebook stories/posts on "WP7.5's Facebook App" &/or from "People hub"

On a computer, you can log into Facebook.com and unsubscribe from a friend's posts by simply clicking the down arrow on top of their post and click "Unsubscribe from so-and-so". I have done this with everyone on my friends list that I don't care to get
posts/updates from (again, I did this on the web, from a computer).

The problem is that the web-based Facebook unsubscription does not translate over to the "WP7.5 Facebook App" or to the "People hub" integrated feature. On top of that, there is no setting or feature I can change in the "WP7.5 Facebook App" or "People
hub" or settings/accounts where I can configure it to unsubscribe from these friends.

No, I don't want to de-friend these people, I'd like to simply unsubscribe from their many MANY posts I don't want to read.

Is there a setting I'm missing, or will this need to be a feature in the next WP7.5 update?

 

Isn't it a legal requirement to have an unsubscribe button in automated emails?

There is an option to unsubscribe:
