One time - recognized means of obstructing accessibility to remote websites is by placing "fake" access (generally in the hosts documents.

Basically, modify/ etc/hosts and also add access similar to this :    facebook.com    apps.facebook.com

FMI on this method, read this ; for even more suggestions of obstructing, read that.

Assuming you have accessibility to your firewall program, You can simply obstruct Facebook is prefixes. You can figure out their ASN from traceroute :

$  traceroute -n -A www.facebook.com
14 [AS3356]  630.713 ms  633.180 ms [AS3356]  629.633 ms
15 [AS3356]  578.959 ms  580.703 ms  579.624 ms
16 [AS32934/AS10753]  577.604 ms  557.247 ms  636.807 ms
17 [AS32934]  633.454 ms [AS32934]  602.556 ms  603.583 ms
18 [AS32934]  634.461 ms [AS32934]  634.431 ms [AS32934]  702.079 ms
19 [AS32934/AS10753]  701.423 ms  700.644 ms  700.937 ms

Which you can validate with devices such as these

$ dig +short AS32934.asn.cymru.com TXT
"32934 | US | arin | 2004-08-24 | FACEBOOK - Facebook, Inc."

Then you would certainly get their prefixes making use of a lookup service

$ lynx --dump https://www.dan.me.uk/bgplookup?asn=32934 2>&1 | grep AS32934
   IPv4 Prefixes seen at AS32934:       [AS32934]
     2620:0:1c00::/40     [AS32934]      [AS32934]      [AS32934]      [AS32934]      [AS32934]      [AS32934]      [AS32934]      [AS32934]       [AS32934]       [AS32934]       [AS32934]

You can after that feed the prefixes right into your firewall program.

Certainly, If I am an established customer, I can make use of any one of the free proxies around providing this entire blog post moot.
