I'm unfamiliar with this phenomenon. In my experience, 500 lb beached whales usually make YouTube channels to toot their own horns and deny being 500 lb beached whales themselves, rather than going after other 500 lb beached whales. Can you provide me with an example of a 500 lb beached whale that has made an entire YouTube channel to criticize other 500 lb beached whales for being 500 lb beached whales?
