In 2023, authors discovered their books had been scraped into Books3, a pirated dataset used to train language models, only after researchers flagged it, not from any notice. That is the harm in miniature: people lose the chance to object until after the fact. My opponent's spam-filter example actually helps me: disclosure can happen at the model or purpose level in plain terms, not as an alert every retrain. "We use your messages to improve spam detection" is one sentence, not noise. Yes, auditing is messy, but the fix is scoped notice, not silence.
