The only clip I remember of him, was how he reiterated his statement that anyone watching loli is a PDF file. That seems to be the complete opposite of your statement. Are you one of those conservatives that just hates gay people and invents shit like this? I heard that the right wing people in america like to try and associate gay people with PDF file stuff.
The problem with nightshade or similar tools is, that if you leave the changes it makes at too weak a setting, then it can be pretty easily removed. For example GAN upscalers that pre date modern “AI”, were pretty much built to remove noise or foreign patterns. And if you make the changes strong enough that they can’t be removed by these models (because so much information was lost), then the image looks like shit. Its really difficult to strike a balance here.
