This page has a list of all global Twitch badges. The list is divided into 2 sections, the first one contains the badges on the bot's global ban list, and the 2nd has all the remaining badges.
If you want to add a badge to the ban list you can use the ==addBadge [ID] command with the badge's ID to add it to your custom ban list in your channel. Or just click the "copy ban command" below.
