Due to his vlogs that basically criticize other YouTubers, iDubbbz has been involved in a number of well-documented fights with his peers. In September 2016, he released an episode of Content Cop criticizing Leafy, a popular video game streamer and vlogger. He called Leafy a bully and taunted him for his "inferiority chin complex". The videos got massive views and Leafy lost some of his subscribers as a result. Another of iDubbbz's famous feuds was the one with a popular vlogger, Tana Mongeau. The beef began in December 2016 when Mongeau criticized iDubbbzTV for its use of derogatory words like n-word and retard.
He responded by teasing Mongeau at a convention in San Francisco in January 2017. Additionally, he released a video on ‘Content Cop’ in which he showed Tana using the ‘N’ word in the past. The video garnered more than 3 million views and Mongeau had to issue an apology. The latest episode of iDubbbzTV's Content Cop was released in October 2017 and focuses on popular YouTuber and rapper RiceGum. The video was accompanied by a diss song known as Asian Jake Paul.
