According to related reports, Reddit has signed a content license agreement that allows the artificial intelligence model of a large AI development company to be "trained" using content submitted by forum users, and Reddit can make $60 million a year through this project, and Reddit has officially refused to respond to this matter. Reddit is an online platform that gathers many users, topics and opinions, and is recognized as one of the largest and most popular online communities in the world due to its large user base and high social interaction. The feature is that anyone can start or join different hot topic discussions, which form small communities called subreddits.

Unsurprisingly, Reddit suffered a strong negative impact within hours of the move being reported, but it is not yet certain what retrospective rights users have for users who are not willing to share their personal data or content with AI models under current laws abroad. According to Tomshardware, while social platforms like Reddit have been making money from user data, there is debate about whether it is legal to provide such data to AI models for a long time.
What's more noteworthy is that Reddit's move could be emulated by other social platforms. This will be a tricky problem for platform users, especially art creators, who don't want their work or personal data to be used to train AI. As a result, many people currently think that AI models are automatic content theft machines, but to make matters worse, there is no real formal law on the use of AI technology in foreign countries.
