I finally blocked Twitter with a Chrome app, but for some odd reason the blank page I get still has that stupid bird.

I was also having trouble with Twitter. How I fixed:

• Go to Twitter
• Open developer tools, go to the application tab
• Click on "clear site data"

After that, Twitter was not able to load anymore

In addition to that, I also added 0.0.0.0 api.twitter.com

If you are using Pi-Hole for blocking just Facebook, you can plug these into the admin web console as wildcard domains:

facebook.com
facebook.net
fbcdn.com
fbcdn.net
fbsbx.com
fbsbx.net
fburl.com
fb.me
fb.com
m.me
messenger.com

Pi-hole wildcard domains match on regex like: (\.|^)facebook\.com$
