In this case, 'They' is WHOzTHEY? — a website built on the idea that 'They say...' claims deserve a real investigation. The creators are the curious minds behind this very page you're reading right now. For once, 'They' showed up and identified themselves.
WHOzTHEY? was born from a simple frustration: people repeat claims constantly without knowing where they came from, and nobody ever stops to ask who 'they' actually are. The site launched with the mission of tracing folk wisdom, old wives' tales, and handed-down sayings back to their real sources — names, eras, and cultures included. It may be the first site dedicated entirely to unmasking the mysterious 'they' behind anonymous collective claims.
