I just developed and published a script to clear your pict-rs object storage from potential CSAM. (github.com)

I noticed a bit of panic around here lately and as I have had to continuously fight against pedos for the past year, I have developed tools to help me detect and prevent this content.

As luck would have it, we recently published one of our anti-csam checker tool as a python library that anyone can use. So I thought I could use this to help lemmy admins feel a bit more safe.

The tool can either go through all your images via your object storage and delete all CSAM, or it canrun continuously and scan and delete all new images as well. Suggested option is to run it using --all once, and then run it as a daemon and leave it running.

Better options would be to be able to retrieve exact images uploaded via lemmy/pict-rs api but we're not there quite yet.

Let me know if you have any issue or improvements.

EDIT: Just to clarify, you should run this on your desktop PC with a GPU, not on your lemmy server!

You might be able however integrate with my AI Horde endpoint for NSFW checking between nginx and Lemmy.

https://aihorde.net/api/v2/interrogate/async

This might allow you to detect NSFW images before they are hosted

Just send a payload like this

curl -X 'POST' \
  'https://aihorde.net/api/v2/interrogate/async' \
  -H 'accept: application/json' \
  -H 'apikey: 0000000000' \
  -H 'Client-Agent: unknown:0:unknown' \
  -H 'Content-Type: application/json' \
  -d '{
  "forms": [
    {
      "name": "nsfw"
      }
  ],
  "source_image": "https://lemmy.dbzer0.com/pictrs/image/46c177f0-a7f8-43a3-a67b-7d2e4d696ced.jpeg?format=webp&amp;thumbnail=256"
}'

Then retrieve the results asynchronously like this

{
  "state": "done",
  "forms": [
    {
      "form": "nsfw",
      "state": "done",
      "result": {
        "nsfw": false
      }
    }
  ]
}

or you could just run the nsfw model locally if you don't have so many uploads.

if you know a way to pre-process uploads before nginx sends them to lemmy, it might be useful
