Following “a series of scandals,” YouTube is taking major steps to overhaul its video review process and ad placement policies. The new guidelines “kick tens of thousands of video makers out” of the ad program by requiring anyone who generates ad revenue to produce 4,000 hours of content and gain 1,000 subscribers in one year, upping the ante from the previous requirement of 10,000 lifetime views.
