While a separate matter from recolored gear, this also always interested me. "Big name" streamers made no attempt to hide their boosting for money ordeals yet I only remember one person ever getting knocked off Twitch, or banned for doing it. There could be more but I only remember 1. By all means I'm fairly certain the guy who organized my groups sales took real money for it, and handed out gold from his own stock piles at times but he never advertised it or put "somethingboost" links on a Twitch page with 1k+ viewers at any given time. But blizzard never seemed to care about people doing it.
