for example instead of:
https://twemoji.maxcdn.com/v/latest/72x72/1f17f.png
you could do:
https://github.com/twitter/twemoji/raw/master/assets/72x72/1f17f.png

Thats not allowed and will be rate limited. Plus they do NOT provide cache headers with requests from Github so the images would be flashing on every page load.

Plus this project is abandoned and does not support the most recent Emojis.

At this point self host (it's small) or use an alternative.
