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!

sure, or a .cpp. But it will still not be anywhere near as good as a GPU. However it might be sufficient for something just checking new images

I'm not really convinced that a GPU backend is needed. Was there ever a comparison of the different CLIP model variants? Or a graph optimized / quantized ONNX version?

I think the proposed solution makes a lot of sense for the task at hand if it were integrated on the pic-rs end, but it would be worth investigating further improvements if it were on the lemmy server end.

For scanning all existing images, trust me a good GPU is necessary. I'm scanning all my backend on a 4090 with 400 threads and I'm still only halfway through after 4 hours.

For scanning newly uploaded images, a CPU might be sufficient but the users might get annoyed at the wait times.
