What’s wrong with it is that advertisers, who are YouTube’s customers, don’t want to advertise next to anything that has to do with sex. They will get very angry if YouTube shows their ads next to a video that has to do with sex. To avoid making their customers angry, YouTube doesn’t show any ads next to videos that have anything to do with sex. Next, because these videos don’t provide any revenue for YouTube they don’t have a big incentive to keep them online. In fact they do have an incentive to be quick at pulling them down.
