Google-owned YouTube has its own brand safety issues. Faced with sporadic pressure from advertisers, they just announced they will increase their content moderators and related staff to over 10,000, reportedly a 25% increase. Let’s put that in context: in 2016, Google parent Alphabet had 72,000 employees. They’re also relying heavily on machine learning and considering which channels should be banned from showing ads. Making things even more complicated, advertisers can’t fully control where their ads run – promotions still appear for companies that announced they were withdrawing all YouTube advertising.
