@sstrader @Daojoan This type of approach is needed for vetting news also. For too long, many in the public have considered photo/videographic evidence to be self-evidently true, or we relied on large impersonal institutions to be the source of truth. In the social media era, many fail to even demand basic journalistic competence (documenting when and where the photo was taken).
We need to carefully rebuild a vetting system based on real interactions that have demonstrated reliability, and make sure we don't reproduce segregation and exclusion that currently dominates many of our institutions.
