The present study examines how different misinformation content moderation approaches influence users' trust, perceptions, and biometric responses related to attention and affective states. We propose a within-subject experimental study with three conditions: platform-driven moderation, community-driven moderation, and no moderation. By comparing these, we assess user reactions to misinformation warnings. Using eye-tracking, galvanic skin response (GSR), and facial expression analysis, we explore how these responses relate to users’ trust in moderation and willingness to engage (like, comment, share) with flagged content. This research contributes to a deeper understanding of how different moderation approaches shape user trust and engagement, informing the development of evidence-based strategies for balancing misinformation control and freedom of expression.
