I posted the other day that you can clean up your object storage from CSAM using my AI-based tool. Many people expressed the wish to use it on their local file storage-based pict-rs. So I’ve just extended its functionality to allow exactly that.
The new lemmy_safety_local_storage.py will go through your pict-rs volume in the filesystem and scan each image for CSAM, and delete it. The requirements are
- A linux account with read-write access to the volume files
- A private key authentication for that account
As my main instance is using object storage, my testing is limited to my dev instance, and there it all looks OK to me. But do run it with --dry_run if you’re worried. You can delete lemmy_safety.db and rerun to enforce the delete after (method to utilize the --dry_run results coming soon)
PS: if you were using the object storage cleanup, that script has been renamed to lemmy_safety_object_storage.py

We Evolve!
There something really satisfying about witnessing a community starting to talk about serious a issue and days later see things already improved.
Lemmy is now the internet, glory to all volunteer devs. Lets make it the best place we possibly can!
I’m curious… How does one even test such a thing before distributing it without having offending files to test against.
Like during the development process of this project, how on earth can you test it properly? 😂
it uses a model that describes a photo, then it searches the generated description for some terms and ranks the image to some levels of safety.
to test it you use a more general filter, for all nsfw for example, and see if the matches are correct.
Hmm, thinking out loud… Wouldn’t that also make it easy to remove scat porn and Hitler + Nazi flag images?
There has been a lot of spam like that on Lemmy and at least the latter is somewhat illegal to host in Germany as well.
yes… maybe.
as the dev said, it flags a lot of false positive. so a human should look at them anyway.
maybe when this is a bit more evolved, we can use it to preprocess posts, and if a post gets flagged for something, a mod / admin needs to approve the post manually.
maybe for CASM, it gets sent to an external service specialized to that stuff, so the mod / admin doesn’t have to look at the images.

seems like clip-interrogator isn’t explicitly supported on apple silicon, I’ll give it a try later
thanks for making this!
Thanks for adding this. I guess I now have my weekend planned for moving Pict-rs to a server with a fast enough GPU and try this out 🤔
You don’t need to move pict-rs to a GPU server. In fact that would be prohibitedly expensive long-term. I suggest you just use your PC to run this against your current pict-rs server, or just rent a GPU server for this time.
I have a server with a smaller Nvidia GPU available. I hope the 3GB vRAM it has will be sufficient.
OK, but just to point out that the script hasn’t been setup to run locally yet. Just through ssh. Making it look for the files locally is my next to-do
Ah, I was already wondering why it would need SSH keys to scan local files 😅 Well, I only have time to look into this on Sunday I think, so no rush.
Is there a reason it needs a PK vs just being able to point it at a local folder and running as a user with wrote access?
It's great that there's now a tool, but this kind of issue is why I'm not considering self-hosting a fediverse service: due to the nature of the beast even a single-user instance effectively becomes a publicly accessible distributor of content that others created/uploaded. I'm sure this could be restricted somewhat (by making the web UI inaccessible for the public), but the federation means that other instances need to be able to get content from the server. That's way to much legal risk for me.
Actually the other instances don't pull content. You push it out instead. Basically if you don't run pict-rs and you don't allow user registreations, you're safe for everything except potential copyright infringement from some text someone might post. If you make your webui inaccessible to anyone but your IP, you protect against even that.
