A new study has found that YouTube's tool to suggest videos can direct young users to content about guns and violence.
一项新的研究发现，YouTube的视频推送工具可能会引导年轻用户观看有关枪支和暴力的内容。
The study was based on an experiment carried out by the Tech Transparency Project.
这项研究是基于技术透明项目进行的一项实验。

Researchers from the group set up two YouTube accounts that simulated online activity that might be interesting to 9-year-old boys.
该组织的研究人员建立了两个YouTube账号，模拟9岁男孩可能感兴趣的在线活动。
The two accounts contained the exact same information.

The only difference was that one account chose only to watch videos suggested by YouTube.
唯一的区别是，其中一个账号只选择观看YouTube推送的视频。

The organization found the account that chose to watch YouTube's suggestions was flooded with graphic videos.

These included videos about school shootings and instructions for making guns fully automatic.

But the study suggests that those tools are failing to block violent content from young users.

She said, "Video games are one of the most popular activities for kids. You can play a game like ‘Call of Duty' without ending up at a gun shop — but YouTube is taking them there."
她说：“电子游戏是最受孩子们欢迎的活动之一。你可以玩诸如《使命召唤》之类的游戏，而不会去枪支店——但YouTube正在把他们带到那里。”
Paul added, "It's not the video games, it's not the kids. It's the algorithms."
保罗补充道：“这不是电子游戏的问题，也不是孩子的问题，而是算法的问题。”
An algorithm is a set of steps that are followed to complete a computing process or problem.
算法是完成计算过程或问题所遵循的一组步骤。
Social media companies use algorithms to predict what content users might be interested in based on past watch history.

The accounts that clicked on YouTube's suggested videos received 382 different gun-related videos in a single month.

The accounts that ignored YouTube's suggestions still received some gun-related videos, but only 34 in total.
那些无视YouTube推送视频的账户仍然收到了一些与枪支有关的视频，但总共只有34个。
A spokeswoman for YouTube defended the platform's protections for children and noted that it requires users under age 17 to get a parent's permission before using their website.

The company noted that it offers several choices for younger viewers that are "designed to create a safer experience for tweens and teens."

Activist groups for children have long criticized YouTube for making violent and troubling content easily available to young users.

They say YouTube sometimes suggests videos that promote gun violence, eating disorders and self-harm.
他们表示，YouTube有时会推送宣扬枪支暴力、饮食失调和自残的视频。

He told the AP that without federal legislation, social media companies must do more to enforce their own rules.
他告诉美联社，如果没有联邦立法，社交媒体公司必须采取更多措施来执行自己制定的规定。
He added, "Children who aren't old enough to buy a gun shouldn't be able to turn to YouTube to learn how to build a firearm, modify it to make it deadlier, or commit atrocities."
他补充说，“那些还不到买枪年龄的孩子不应该在YouTube上学习如何制造枪支，如何对其进行改装以使其更致命，也不应该犯下暴行。”
