Information handling practices of LLM agents are broadly misaligned with the contextual privacy expectations of their users. Contextual Integrity (CI) provides a principled framework, defining privacy as the appropriate flow of information within context-relative norms. However, existing approaches either double inference cost via supervisor-assistant architectures, or fine-tune on narrow task-specific data. We propose extracting normative simulacra (structured representations of norms and infor

People are increasingly concerned that data collectors can use information about them to subtly influence their decision-making—what is often called “online manipulation”. To further efforts at combating such strategies, this paper defines “online manipulation” and explores the harms it threatens.
