RoaR
Recall over all Reports
Meta's "new north star metric for defensible user reporting enforcement", introduced during the 2023 child safety task force. It captures "whether we reviewed a report in the first place and whether a rep is likely to action it correctly", and the source document puts initial results on content RoaR at about 24%.
