very easy: don't follow CASM accounts, only view notes from those you follow.
#asknostr among the problems that Nostr faces, the child porn problem is a very, very, very bad problem.
A VERY bad problem.
What is the current thinking among developers about how to deal with this?
Nobody likes censorship, but the only solution I can think of (SO FAR) is running an image identification service that labels dangerous stuff like this, and then broadcasts a list of (images, notes, users?) who are scoring high on the "oh shit this is child porn" metric. Typically these systems just output a float between zero and 1, which is the score....
Is anyone working on this currently?
I have a good deal of experience of running ML services like image identification at scale, so this could be something interesting to work on for the community. (I also have a lot GPU power, and anyway, if you do it right, this actually doesn't take a ton of GPUs to do even for millions of images per day....)
It would seem straightforward to subscribe to all the nostr image uploaders, generate a score with 100 being "definite child porn" and 1 being "not child porn", and then broadcast maybe events of some kind to relays with this "opinion" about the image/media?
Maybe someone from the major clients like nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q or #coracle or nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg or nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 has a suggestion on how this should be done.
One way or another, this has to be done. 99.99% percent of normies, the first time they see child porn on #nostr ... if they see it once, they'll never come back.....
Is there an appropriate NIP to look at? nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 ? nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft ? nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr ?

That's kind of the solution indeed. But we still have to fix reply spam.
I think I'm the only one who noticed, but someone dropped 2 naked toddler pics in the replies to this thread.
Yeah, it's totally fucked up. We need to fix this.
By convention replies are sent to the thread root's defined "read" relays.
I think it's fair to assign responsibility to the thread creator for picking unsafe relays. But of course it could also be your client's fault for using random public relays or something like that. Relays are the only way to filter content properly on Nostr, clients and users should start to be more mindful of that.
In my case I use Gossip with the nuclear option of only reading replies from the relays I specify manually, so even if the thread creator is evil I won't see evil replies, but this is not the ideal solution either.
Filtering out replies from people with low WoT score like Coracle does also works fine. It can't prevent your computer from beeing flooded with spam, but at least in the short term it would have filtered all these evil targeted attackers.
The problem starts, when you use search and hashtags.
They use popular hashtags sometimes
Hashtags are stupid.
Search I don't know, never got any such results from any search I made. But anyway search relays should be more strict on content they accept, they can't be just open to anyone to flood, this will never work.
