Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

Follow along...

    table <blocked_zones> persist file "/etc/pf-files/blocked_zones"
2. In the block-section add early:
    block in quick proto tcp from <blocked_zones> to any port { 22 80 }
