Facebook’s engineers completely retooled the site’s interface to make videos as easy as possible to watch and share. All you have to do is scroll through your News Feed and you’ll be introduced to countless videos that start to play as they pop up on your screen.

Because of this unprecedented ease in discovering and watching video content, Facebook is giving Google-owned YouTube a run for its money. Literally. As Fortune’s Erin Griffith reports:

Facebook drives nearly a quarter of all web traffic. The company’s recent video improvements will likely push those numbers even higher. And while the surge will help the social network do even more to entertain bored millennials, there is also big money at stake. Facebook is, after all, in the advertising business. The new video-tech innovations not only encourage its users to spend more time on the site, but they also make it easier for marketers to reach those users.

But Facebook’s video efforts are drawing controversy lately. Some observers say the social network is littered in video content lifted from its original source, meaning the content creators aren’t seeing a dime for their work. And while YouTube has built-in mechanism for content creators to report such theft, Facebook has no such solution.

YouTube star Hank Green wrote a blog post about this issue, known as “freebooting,” entitled “Theft, Lies, and Facebook Video.” In it, he outlines why he believes Facebook’s video practices are unethical. Green cites a report from ad agency Ogilvy and Tubular that found over 70% of Facebook’s top performing posts came from other sources like YouTube.

If those users had embedded the YouTube videos on Facebook, this wouldn’t be an issue. Instead, these are videos that have been taken from other sites and uploaded to Facebook’s native player, giving that Facebook page the credit rather than the rightful copyright holder. Facebook’s algorithm favors videos that are uploaded natively, a setup that Green says encourages intellectual property theft.

YouTube has a system to deal with this type of thievery called Content ID. Soon after Google bought YouTube, it built a database of registered intellectual property and began monitoring all new uploads to ensure they don’t infringe on someone else’s copyrighted material. If they do, the video will either be removed or the original poster can collect advertising money from it.

But Facebook has no such system. And there’s no way to search for videos on the website; you just have to wait and see if you happen to spot your stolen property, Green says. If Facebook is serious about courting video content creators, expect it to roll out some mechanism to deal with this problem in the future.

Update: A Facebook spokesperson sent the following comment to Fortune:

We take intellectual property rights very seriously. This is not new to Facebook. We have a number of measures in place to address potential infringements on our service. For years we’ve used the Audible Magic system to help prevent unauthorized video content. We also have reporting tools in place to allow content owners to report potential copyright infringement, and upon receiving a valid notice we remove unauthorized content. We also suspend accounts of people with repeated IP violations when appropriate.

As video continues to grow on Facebook, we’re actively exploring further solutions to help IP owners identify and manage potential infringing content, tailored for our unique platform and ecosystem.

This is a significant technical challenge to solve, but we have a team working on it and expect to have more to share this summer. As with all products and experiences on Facebook, we’re listening to feedback, and want to continue to improve our content management tools for people and publishers.
