Reddit has filed lawsuits against Perplexity AI and three other companies, accusing them of unauthorized data scraping from the Reddit website. According to the lawsuit filed in Manhattan federal court on Wednesday, data scraping companies Oxylabs UAB, AWMProxy, and SerpApi collected Reddit data through Google search results for the purpose of reselling the data. The lawsuit alleges that Perplexity purchased this data from at least one of these companies. With the rise of AI models that rely on large amounts of data for training and providing relevant results, Reddit's growing data repository has become a valuable commodity. Reddit has entered into agreements with OpenAI and Alphabet to use Reddit data for training, but has also taken legal action against some companies that have not signed formal agreements with them. Earlier this year, Reddit also filed a similar data scraping lawsuit against Anthropic in a San Francisco court.
