they’re not really tailored to that… also, it wasn’t hard to photoshop naked pictures that long ago.
but now these “tools” are neural net models… there are thousands of them hosted on dozens of source code repositories… and like op said, you can run it on any high end gaming gpu.
you can’t outlaw source code like that.
you could sue this one app maker and try to require that they prove consent and detect underage photos… totally a good idea, but it would do little to stop it…
they’ll just use a different app
i think they could prosecute the other people making and distributing the pictures though.
