Alliance character "Spiritroar" is banning players on the horde (playing on alt "Spiritboar") World channel and only unbanning them if they follow his stream on Twitch. His friend Normander and himself (Spiritboar on horde) are doing this together. Video proof below. Not sure if this is against the rules, but I'm sure there is something that can be done.
