While the company has historically dismissed these accusations as disingenuous or misunderstandings, a new report shows that not only is the practice still happening, but it may actually be getting worse.

Perplexity is allegedly scraping websites it's not supposed to, again

engadget.com Unknown 2025-12-10 00:11:10

Web crawlers deployed by Perplexity to scrape websites are allegedly skirting restrictions, according to a new report from Cloudflare. Specifically, the report claims that the company's bots appear to be "stealth crawling" sites by disguising their identity to get around robots.txt files and firewalls. Robots.txt is a simple file websites host that lets web crawlers know if they can scrape a websites' content or not. Perplexity's official web crawling bots are "PerplexityBot" and "Perplexity-Us

Perplexity is using stealth, undeclared crawlers to evade no-crawl directives

5 min read We are observing stealth crawling behavior from Perplexity, an AI-powered answer engine. Although Perplexity initially crawls from their declared user agent, when they are presented with a network block, they appear to obscure their crawling identity in an attempt to circumvent the website’s preferences. We see continued evidence that Perplexity is repeatedly modifying their user agent and changing their source ASNs to hide their crawling activity, as well as ignoring — or sometimes

Some return from here to try another area (e.g., machine learning, which pays more and is easier to understand but less interesting than signal processing).

Lately, like everyone else, I've been looking at AI a lot more closely. While it's nifty and getting genuinely useful, it can still blunder, like the time Google's AI Overviews recommended users to eat "at least one small rock per day."
