Some of you may have noticed a lot of people freaking out about CSAM and a bunch of communities closing, instances restricting registrations, turning off image uploads or shutting down completely. It's a bit of a chaos.

Fortunately your admin has been fighting this fight for the past year so I have developed some tools to help me out. I repurposed one of them to cover lemmy images

Using this approach, I've now turned on automatic scanning of new uploads.

What this means for you is that occasionally you will upload an image for a post and it will stop working after a bit. C'est la vie. Just upload something else. Changing format or slightly altering the image won't help you.

Also, sometimes you might see missing thumbnails on post from other communities. Those were the cached thumbnails hosted by us. The original images should still work in those cases.

Unfortunately this sort of AI scanning is not perfect and due to the nature of the beast, it will catch more false positives but to an acceptable degree. But I find that this is OK for a small social network site run as a hobby project.

Cool? Cool.

behavior like this baffle me. I wonder what they stand to gain by spamming CSAM? Purely destructive and psychopath behavior :|

Most likely 4channers. They do stuff like that constantly and laugh at the panic

Very cool! Personally I'd think even blocking any pictures of children on the website, as those are almost always posted by adults without real consent and rest of the time children who do not understand the consequences of uploading their photos to internet.

But this is very cool!

You should also log when, who, and from where these images are being uploaded.

[–] db0@lemmy.dbzer0.com 2 points 2 years ago

That's not possible currently

Far better to have some false positives than any false negatives

Is that Cardinal Lemmy Killmeister?

Defederate that tankie shit. Literally one of the main rules of this instance is no tankie shit, yet HB is here.

I happen to agree with this somewhat blunt individual here. They're annoying, and though I'm not generally in favor of censoring even people as abhorrent as they, when it becomes so prevalent and aggressive that it is tantamount to spam, I think it is warranted. The genocide denial and all that is just icing on the cake to me, frankly.
