Blocking images on PieFed - coming soon

PieFed uses PDQ hashing to generate a fingerprint of an image and can use that fingerprint to detect other posts that use the same or fairly similar images, for moderation purposes. Hashes are added to a block list which stops the image from being re-posted in future.

Currently each instance maintains their own list of hashes. But in the near future it will be possible to share them so that if I see something horrific & ban it then the ban will be automatically applied to your instance too and then you won't need to see the image at all.
