According to Dice’s website:
YouTube has deleted my channel, YouTube.com/MarkDice and removed all 800+ of my videos for what they said were “Severe Terms of Service Violations” which is a lie and they have disabled the dispute feature, which usually allows users to file a dispute when videos get removed. Over 55 million views total, 3-5 million per month, 265,000 subscribers, and over 800 videos GONE! They deleted my BACKUP channel a few hours later for the same reason. This happened less than a week after YouTube granted authority to 200 “super flaggers,” many of which are government agents, who now have the power to remove any video or channel they want to for any reason. I’m serious. Look it up.
