"We've also terminated over 400 channels for the comments they left on videos and reported illegal comments to law enforcement,".
YouTube said it had disabled comments on millions of videos that "could be subject to predatory comments".
According to Wired, pedophiles were making sexually explicit comments on videos of "children showing their exposed buttocks, underwear and genitals", and "little girls playing Twister, doing gymnastics, playing in the pool and eating ice lollies", which received millions of views.
DeFranco also said that the problem is not only with YouTube.
A YouTube spokesperson sent a statement to TechCrunch that said "Any content - including comments - that endangers minors is abhorrent and we have clear policies prohibiting this on YouTube". "I was pleased to see YouTube's recent announcement that it will no longer recommend videos that violate its community guidelines, such as conspiracy theories or medically inaccurate videos, and encourage further action to be taken related to vaccine misinformation", he said in a statement.
"There's more to be done, and we continue to work to improve and catch abuse more quickly", a YouTube spokesperson said. The company has been deleting comments and any channels directly associated with them.
In 2017, AT&T, Verizon and Johnson & Johnson stopped YouTube ad spending after some ads ran over videos allegedly supporting ISIS.
Charges against singer R. Kelly to be announced this afternoon

Google does not specify its revenue from YouTube.
In January, YouTube announced a change to its content-recommendations system aimed at reducing the recommendation of "borderline content and content that could misinform users in harmful ways".
YouTube has no choice. Numerous videos that were being flocked to by pedophiles were young girls doing gymnastics. If it wants to stop business interests from taking a hit, it must remove questionable material.
However, the survey also found that marketing professionals ranked YouTube as the least brand-safe platform out of eight possible choices, behind Twitter, Facebook, Instagram, search, other publisher sites, LinkedIn, and Snapchat. "We also need to fight to have the developers of social media platforms held responsible when they do not assure that age restriction are followed and when they do not remove inappropriate and/or unsafe material when reported".
Other videos show flashes of exposed genitals, or feature children - a lot of them girls - doing the splits or lifting up their tops to show their nipples.
The push to stop the spread of anti-vaccination content comes amidst social media companies' large efforts to fight misinformation of all types, but particularly regarding politics and social issues.
