isop no longer works in the twitch IRC servers. All users including the broadcaster no longer show up as OP in the user list.
Twitch require the use of message tags now to check for moderator / broadcaster / sub / VIP:
(broadcaster isin $msgtags(badges).key)
But the issue is, using (moderator isin $msgtags(badges).key) on the bot for the bot checking themselves doesn't work, as it can't check it's own messages, and because it doesn't run the command itself (and can't run it's own commands), and in turn doesn't see it's own replies in the mIRC chat room, there's no easy way of checking the tags on the bot.
