Open source project fools AI scrapers with poisoned font
The Register
A design studio released ShieldFont, an open-source font that uses glyph substitution to replace words with grammatically equivalent alternatives, making raw HTML appear as gibberish to AI scrapers while remaining readable to humans. The technique creates about 250 grammatical word pools and replaces roughly a quarter of words in text, with web font files compressed to around 800 KB. The poisoned approach aims to introduce uncertainty into training data rather than simply blocking scrapers, though it can be defeated by OCR, targeted AI, and may cause SEO penalties.
