      Tbh I’m not sure, I vaguely remember that hashes did play a role in how chatcontrol works, but I think it wasn’t looking just for 1:1 match of known illegal content, but also for some signs?

      According to the Swiss Federal Police, 80% of the reports they receive (usually based on the method of hashing) are criminally irrelevant. Similarly in Ireland only 20% of NCMEC reports received in 2020 were confirmed as actual “child abuse material”.
