Of course, the small bit of information Hawley released doesn't at all tackle the challenge of defining when a video "features minors." It's also overly simplistic in the way it describes "professionally produced videos" — plenty of amateur content on YouTube has production value and quality that can come close to matching what more traditional outlets create.
And despite the lack of specificity released thus far, it's pretty clear YouTube isn't doing enough to deal with this issue. As the New York Times explained, YouTube's algorithm can push users from erotic videos to recommended videos with women who get younger and younger, eventually surfacing videos of girls under 10 years old wearing bathing suits. It's a huge problem, and the flaws of YouTube's algorithm isn't limited just to serving individuals looking for videos of young children.
It's also been cited as a major contributing factor in the spread of fake news and conspiracy theory videos -- earlier this year, searches for Supreme Court Justice "RBG" quickly lead people down a path to fake conspiracy theory content, for example. YouTube said in January that it would stop recommending such videos, and just yesterday it announced it would finally start removing videos denying that events like the Holocaust or the Sandy Hook shooting happened. This is all without even mentioning the self-inflicted gunshot wound YouTube gave itself this week by deciding not to remove right-wing commentator Steven Crowder's videos after he continually subjected Vox journalist Carlos Meza to hate speech. (YouTube eventually decided to de-monitize Crowder's channel, something that will almost certainly have no effect on his rhetoric.)
As always, the sheer volume of content that is uploaded to YouTube every day makes this policing incredibly challenging, and lately there have been plenty of calls for more government regulation of tech giants like YouTube's parent company Google. Whether Senator Hawely's bill has much of a shot at success certainly remains to be seen, but it seems likely we'll see more potential legislation in the same vein going forward.
