Block facebook network segments - web content filtering at OSI layer 3

Hello networkers. 
Are you guys interested to filter the whole facebook segment at your company or at home?
Do you want to re-route or block facebook traffic at L3 level? 
In case you have plenty of free time and willing to make a little bit of research you will find out that Facebook inc. is currently using 3 public AS world wide only:
AS 32934
AS 54115
AS 63293
(I used this url to validate public AS list: )

Anyways, within this ranges they have bunch of public network segments obviously. I worked one by one to bring you here the supernets matching ALL Facebook inc. segments. 
Here we go: 

Table updated Friday November 13th, 2020. 
In case you find another supernet or segment I skipped please add it in the comments below. Also if you have other public AS list more reliable please share. Thank you
