TikTok在美国推出名为“脚注”的新功能，允许用户为视频添加背景信息或纠正性内容，以识别和标记不准确或具有误导性的信息。该功能类似于X（前身为Twitter）和Meta的社区笔记，用户可以提交带有可靠来源链接的解释，并由其他用户评分。若获得足够支持，该脚注将显示在相关视频下方。此举旨在应对TikTok作为年轻人新闻来源日益增长的影响力，并配合平台现有的自动化和人工审核机制，共同打击虚假信息。要参与脚注功能，用户需在美国、使用至少六个月且无社区违规记录。

📊 **“脚注”功能上线，赋能用户参与内容审核**：TikTok在美国推出“脚注”功能，效仿其他社交媒体平台，允许用户为视频添加背景信息或纠正性内容，旨在识别和标记不准确、误导性或经过编辑的媒体。这一众包工具使用户能够主动参与到平台内容的审核过程中，提升信息的可信度。

🔗 **引入可靠来源机制，提升信息准确性**：用户在提交“脚注”时，被要求提供指向“可靠来源”的链接以支持其观点。尽管TikTok初期允许用户自行选择来源，但平台后续将对这些来源进行评估，以期建立一个更具公信力的信息验证体系，并通过用户评分机制来决定脚注的最终采纳。

🚀 **用户参与门槛与功能局限性**：要成为“脚注”的贡献者，用户需满足在美国、使用TikTok至少六个月且无近期社区违规记录等条件。初期，“脚注”仅会显示在原始视频上，不适用于Duets或Stitches，也不包含广告内容，这在一定程度上限制了其覆盖范围。

⏱️ **应对虚假信息传播的速度挑战**：该功能的有效性很大程度上取决于TikTok能否有效防止系统被滥用，以及“脚注”提交、审核和发布的速度。鉴于有害信息可能在短时间内迅速传播，快速有效的审核机制对于“脚注”功能发挥其应有的作用至关重要。

Fact-checkers, start your engines.

TikTok is launching a new "footnotes" feature in the US on Wednesday that allows users to add context or corrective information to videos.

The crowdsourcing tool is similar to X (formerly Twitter) or Meta's community notes. It lets users flag videos they believe contain false claims, information that needs clarification, or media that has been edited or artificially generated. Other users then rate the submission's accuracy and helpfulness. If enough support it, it could get added below an offending video.

The footnotes feature arrives at a key moment for TikTok, which has grown into a popular news source for young people. Last year, 17% of US adults said they regularly get news on the site, up from 3% in 2020, according to the Pew Research Center.

TikTok is not relying solely on footnotes to address misinformation.

The company said it uses automation and human moderators to track down false content, working with a global network of fact-checkers to identify misinformation in different markets. But for app users, footnotes may quickly become one of the more visible forms of content review happening on the app.

To start posting footnotes, a user must be based in the US, have been on the app for at least six months, and have no recent community violations on their record. The company said it had registered around 80,000 participants to seed the product at launch.

One challenge that may crop up for TikTok is defining what is or isn't good information in a footnote (an area of contention in the US media landscape where political divisions run deep).

When submitting a footnote, TikTok asks users to provide a link to a "reliable source" to support their claim, though TikTok isn't dictating what is or isn't reliable.

"In the beginning, we're letting our users choose which links to upload and after we go live, we'll be taking a look at some of the sources that come in," Erica Ruzic, TikTok's global head of integrity and authenticity product, said on Tuesday at an event hosted at the company's New York offices. "We will let our users decide what they're deeming an authoritative source to begin."

Initially, footnotes will only appear on the original offending video, which means duets or stitches won't get flagged. They also won't appear on content from advertisers.

The effectiveness of the program may depend on TikTok's ability to prevent its system from being gamed, as bad actors might try to flood the zone with misinformation on a particular topic, Angie Drobnic Holan, director of the International Fact-Checking Network, said during a Tuesday panel at TikTok's offices.

The speed at which a footnote is submitted, reviewed, and posted will also be an important factor in the program's impact.

"When bad content that's harmful goes viral, it doesn't go viral in two weeks, it goes viral in one hour," Roberta Braga, founder and executive director of the Digital Democracy Institute of the Americas, said during the panel.
