ShieldFont disrupts AI scrapers by serving them nonsense while humans read normally

New font turns ordinary webpages into nonsense for AI scrapers

ShieldFont replaces 24.5% of words with unrelated synonyms, staying readable while poisoning AI training—90% of pages fail scraper filters. Scrapers choose between poisoned data or 5-13x costlier OCR, raising unauthorized AI training costs and enforcing creator consent rights.
