Reddit has updated its robots.txt file to block most search engines, including Bing and DuckDuckGo, from crawling its content, effectively allowing only Google to index recent posts. This move follows a $60 million annual licensing deal with Google that grants the tech giant access to Reddit's data for training its AI models. As a result, users on alternative search engines will find it increasingly difficult to access current Reddit content, sparking concerns over Google's growing dominance in search. The decision to restrict crawling is part of Reddit's strategy to monetize its data and prevent unauthorized scraping, particularly by AI companies. Reddit's chief legal officer indicated that this change signals to non-paying search engines that they should not access Reddit's data. The situation has ignited discussions about potential monopolistic practices in the search engine market and the implications for users seeking diverse search experiences.
