Reddit Sues Perplexity for Content Theft
Reddit filed a lawsuit alleging illegal scraping of Reddit and Google content by Perplexity and a group of scraper firms (Oxylabs UAB, AWMProxy, SerpApi) to power AI answers and related services, with the data later sold to third parties. Reddit claims Perplexity is involved with at least one defendant and accuses the firms of bypassing Reddit and Google controls to obtain copyrighted user content. The complaint states Reddit receives high millions of dollars from Google and OpenAI for data sharing and describes the data ecosystem as a key source for AI developers. The Information and Forbes are cited regarding connections between Perplexity, SerpApi, and scraped content, and Forbes alleges plagiarism by Perplexity in 2024. Perplexity denies the allegations and says it will vigorously defend user access to public knowledge. The case could set an important precedent for data rights and AI training data governance in the digital ecosystem.
