See what channels a user is a VIP/Moderator in.
Twitch allows any user to see who's a Moderator or VIP in any channel by typing /mods or /vips. Twitch Database just adds an interface to display them all in a single page.
Channels are only updated while they're live and have 3+ viewers. If a channel doesn't meet those requierments for 3 months, they will no longer show up in results.
