# New font tricks AI scrapers into reading gibberish

*2026-08-12 · Source: [Ars Technica](https://arstechnica.com/ai/2026/08/new-font-turns-ordinary-webpages-into-nonsense-for-ai-scrapers/)*

A Brazilian type studio and a Copenhagen foundry released ShieldFont, a free open-source web font that uses OpenType glyph substitution to show human readers one sentence while scrapers extract a different, grammatically valid one. Site owners can apply it selectively to protect key content while leaving the rest indexable.

**Why it matters:** It's a targeted, opt-in alternative to blanket anti-scraping measures like robots.txt or paywalls, fitting a growing pattern of publishers actively poisoning training data rather than just blocking crawlers. Adoption will hinge on how much SEO reach site owners are willing to trade for protection.

**Topics:** research, policy
