Captchas have largely vanished from the web in 2025, replaced by invisible tracking systems that analyze user behavior rather than asking people to decipher distorted text or identify traffic lights in image grids. Google launched reCaptcha v3 in 2018 to generate risk scores based on behavioral signals during site interactions, making bot-blocking technology "completely invisible" for most users, according to Tim Knudsen, a director of product management at Google Cloud. Cloudflare followed in 2022 by releasing Turnstile, another invisible alternative that sometimes appears as a simple checkbox but actually gathers data from devices and software to determine if users are human. Both companies distribute their security tools for free to collect training data, and Cloudflare now sees 20% of all HTTP requests across the internet. The rare challenges that do surface have become increasingly bizarre, ranging from requests to identify dogs and ducks wearing various hats to sliding a jockstrap across a screen to find matching underwear on hookup sites.

An anonymous reader shares a report: The Content Overseas Distribution Association (CODA), an anti-piracy organization representing Japanese IP holders like Studio Ghibli and Bandai Namco, released a letter last week asking OpenAI to stop using its members' content to train Sora 2, as reported by Automaton. The letter states that "CODA considers that the act of replication during the machine learning process may constitute copyright infringement," since the resulting AI model went on to spit out content with copyrighted characters. Sora 2 generated an avalanche of content containing Japanese IP after it launched on September 30th, prompting Japan's government to formally ask OpenAI to stop replicating Japanese artwork. This isn't the first time one of OpenAI's apps clearly pulled from Japanese media, either -- the highlight of GPT-4o's launch back in March was a proliferation of "Ghibli-style" images. Altman announced last month that OpenAI will be changing Sora's opt-out policy for IP holders, but CODA claims that the use of an opt-out policy to begin with may have violated Japanese copyright law, stating, "under Japan's copyright system, prior permission is generally required for the use of copyrighted works, and there is no system allowing one to avoid liability for infringement through subsequent objections."
