Except I distinctly remember Facebook having customizable feeds in 2013. I was able to separate friends by groups to their own specific feeds and block them from my main feed. I havent been able to figure out how to get that feature back since I forgot about it. My best guess is I either deleted those lists or Facebook pulled back the feature due to lack of use.

Edit:

Here's a link to someone asking for help when I guess they started to pull the plug on custom friend feeds:
