New font tricks AI scrapers into reading gibberish

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.
