This suggests that user.broadcaster is not true.
Or user doesn’t contain what it is supposed to contain
Or user is derived from tags and is using the deprecated broadcaster tag instead of testing badges
Or user is derived from tags and is malfunctioning.
But in this case why would a mod or a broadcaster user a bot command when they can just do /followersoff themself. Basically doesn’t make sense to ask the caster or a mod to sue a bot command when the caster or a mod can do it themself. You have needless reimlemented a channel command.
