Why context-aware matters

A plain word list flags "this game is sick" or medical text full of anatomical terms. The Profanity API runs a five-layer pipeline that scores intent, so "die" in a gaming taunt and "die" in a real threat are handled differently. Pick a context and the engine adjusts strictness automatically.
