- This study examines how online behavior changed following the April 2022 introduction of IP-based geolocation disclosure on Sina Weibo. Unlike full identity disclosure, geolocation disclosure reveals an identity-relevant but indirect cue, making users partially identifiable while preserving substantial anonymity. Using 2,245,780 comments associated with 36,470 posts, we analyze post-policy changes in comment sentiment, comment length, comment volume, and repost volume. Observed comment sentiment is more positive after implementation, with larger post-policy increases in institutional-account contexts and among verified commenters. We find no statistically significant changes in comment length, comment volume, or repost volume. Horizon-specific estimates indicate that several responses are concentrated near implementation or evolve non-monotonically. Overall, the evidence is clearest for expressive tone. The sentiment response varies across interaction contexts, while several outcomes exhibit temporal heterogeneity.
