In 2018, YouTube will raise its content moderation workforce to over 10,000 employees, all of whom will be tasked to screen videos for trouble spots and simultaneously train YouTube's machine learning algorithm to look for and remove problematic children-centric content.
Last week, it removed 150,000 videos featuring children, after users posted lewd comments about the kids.
According to Wojcicki, YouTube spent past year "testing new systems to combat emerging and evolving threats" and invested in "powerful new machine learning technology", and is now ready to employ this expertise to tackle "problematic content".
More staff will be hired to monitor content, taking the total number of people across Google working to enforce content policies to over 10,000 in 2018, the company said.
The reports led several big brands including Mars and Adidas to pull advertising from the site.

It's worth noting that Smith-Schuster did apologize on Twitter after the game, saying "he didn't mean to hurt" Burfict. Brown also said, "I liked that, I liked that", when discussing the block, per Chris Adamski of the Tribune-Review.
Ms Wojcicki said that staff had reviewed almost two million videos for violent extremist content since June.
Wojcicki has also promised to take actions to protect advertisers and creators from inappropriate content, which she believes requires a new approach to advertising on YouTube, carefully considering which channels and videos are eligible for advertising. In addition, YouTube would also "apply stricter criteria, conduct more manual curation, while also significantly ramping up our team of ad reviewers".
"In the last few weeks we've used machine learning to help human reviewers find and terminate hundreds of accounts and shut down hundreds of thousands of comments", she said. The website said it is drastically increasing the number of people in charge of overseeing content.
This is helping to train the company's machine learning technology to identify similar videos, which is enabling staff to remove almost five times as many videos as they were previously, she said.
YouTube's parent company, Google, also promises to continue developing advanced machine-learning technology to automatically flag offensive content for removal. "But no matter what challenges emerge, our commitment to combat them will be sustained and unwavering", she declared.
