Submitted title was "Japan: Using Nightshade, etc. tools to disrupt AI training is illegal" but that's too far from what the OP says, so I've attempted to put a shortened version of the latter up there instead. In a case like this, that's the best way to follow the guideline "Please use the original title, unless it is misleading or linkbait; don't editorialize." - https://news.ycombinator.com/newsguidelines.html
