Reddit is using LLMs to solve a problem LLMs largely created

Reddit 正在利用大语言模型（LLM）解决由大语言模型引发的问题

It’s easier than ever for bad actors to spew spam across the internet as powerful large language models (LLMs) become effortlessly accessible. If you’ve spent about 10 minutes on the internet in the last few years, you will know that this means spam and bot content have become an even bigger problem than they already were. 随着功能强大的大语言模型（LLM）变得触手可及，不法分子在互联网上散布垃圾信息变得前所未有的容易。如果你在过去几年里哪怕只花 10 分钟上网，你就会知道，这意味着垃圾信息和机器人内容已经成为了比以往更严重的问题。

Reddit says it developed tools with LLMs to cut down on spam, much of which was created with LLMs in the first place. It’s a bit ironic, but in the AI era, platforms have no choice but to fight fire with fire. Reddit 表示，他们已经开发出利用大语言模型的工具来减少垃圾信息，而这些垃圾信息很大程度上最初就是由大语言模型生成的。这听起来有些讽刺，但在人工智能时代，各大平台别无选择，只能以毒攻毒。

According to the platform, Reddit blocks 23 million spam views per day and catches about 25,000 new spam posts and comments each day. Social platforms have been building automated spam reduction tools for years, but Reddit says these updated tools are catching spam at a higher rate. 据该平台称，Reddit 每天拦截 2300 万次垃圾信息浏览，并捕获约 2.5 万条新的垃圾帖子和评论。社交平台多年来一直在构建自动化的垃圾信息减少工具，但 Reddit 表示，这些更新后的工具捕获垃圾信息的效率更高。

“We leverage LLMs to catch the highly subtle, coordinated patterns of fake behavior and artificial hype that older systems once missed,” a Reddit blog post says. The company claims it reduced users’ exposure to spam by 20% from January to March compared with the prior three months. Reddit 的一篇博客文章写道：“我们利用大语言模型来捕捉那些过去旧系统无法识别的、极其隐蔽且协调一致的虚假行为和人为炒作模式。”该公司声称，与前三个月相比，从 1 月到 3 月，用户接触到垃圾信息的比例降低了 20%。

Platforms like YouTube, Meta, and Instagram allow users to post AI-generated content so long as they disclose it, and TikTok is going as far as letting users toggle how much AI-generated content they want to see. If platforms are able to detect AI-generated content faster, that also means that they have the potential to flag violative content like hate speech more quickly. YouTube、Meta 和 Instagram 等平台允许用户发布人工智能生成的内容，前提是必须进行披露；TikTok 甚至允许用户自行调节想要看到的人工智能生成内容的数量。如果平台能够更快地检测出人工智能生成的内容，这也意味着它们有潜力更迅速地标记出仇恨言论等违规内容。

But platform experts have continually reminded us that AI content moderation must be paired with human moderation to get the most effective results. 但平台专家不断提醒我们，人工智能内容审核必须与人工审核相结合，才能获得最有效的成果。
