Source of Italy’s Elevated Harm Exposure

Identify whether the elevated harm exposure observed among Italian TikTok personas is attributable to country-specific content supply or to per-language moderation capacity.

Background

Italy exhibits the highest measured passive harm rate across the age personas, and the analysis shows that the difference is concentrated in Italy-exclusive content rather than globally circulating videos. The authors also find that the Italian pattern persists for English-language videos, reducing the likelihood that translation alone explains the result. However, external observation of TikTok cannot distinguish whether the country-specific content pool reflects differences in available content supply or differences in moderation capacity for the relevant language.

References

The pattern therefore points to the country-specific slice of the pool TikTok serves to Italian accounts rather than to translation artifacts or annotator thresholds; whether that slice reflects content supply or per-language moderation capacity \citep{tonneau2025languagemoderation} is not identifiable from the outside.
