Whitelisted categories are the categories that are somewhat whitelisted from antinuke. Let's say, you have a ticket bot, Ticket Tool for example. You can make it so that Ticket Tool will create tickets under a specific anpanic whitelisted category. If you decide that you don't need to do that, the bot will get quarantined for deleting and creating channels that are meant for tickets. Wick is a bot and it can't differentiate between which channels are genuine and which are not.
