government and university domains hosting adult-AI spam, documented
The Parasite Files: Spam PDFs on Government and University Sites Are Gaming Adult AI Search
During routine daily monitoring of adult AI search results, Sindexed documented a network of spam PDFs hosted on United States military, university, and government websites — including West Point, UC San Diego, the University of Kentucky, and the State of California — ranking in Google for queries like “best AI porn generator.” The PDFs are uploaded through unsecured public web forms whose attachment directories are publicly crawlable. The institutions are victims, not participants: their domain authority is being hijacked to rank affiliate content that outranks legitimate results.
How the scheme works
Every observed host runs a public-facing form (contact, application, or submission forms built on WordPress plugins like Contact Form 7, WPForms, Forminator, and Ninja Forms, or Drupal webforms) that accepts file attachments and stores them in a web-accessible directory. Spammers upload keyword-stuffed PDF listicles as “attachments,” the files inherit the institution’s domain authority, and Google indexes and ranks them — sometimes in the top 10 — for commercial adult AI queries. The PDFs funnel readers to affiliate links. The same template appears across hosts, indicating a single coordinated operation.

A ResearchGate-hosted PDF from the same template family was also observed at #4 for “best ai porn generator” (July 15). We retain dated URL records for every observation and will share them with affected institutions, researchers, or reporters: support@sindexed.com.
Why it matters
For the institutions, it is a security and reputation failure that is trivial to fix (restrict or de-index form-upload directories). For users, it means top search results for adult AI queries are frequently undisclosed affiliate spam wearing a .gov or .edu badge. For the industry, it means legitimate platforms and reviewers are being outranked by content that no one stands behind. We re-check these hosts as part of daily monitoring and will update this page as the network moves or is purged.
Responsible disclosure and citation
We name hosts because the files are already public, indexed, and ranking — the harm is ongoing and visibility accelerates cleanup. Affected institutions can reach us for full URL lists at support@sindexed.com. All findings free to cite with attribution to Sindexed and a link (CC BY 4.0).
