I clicked the link. Those images look like modern, colorful and expressionistic art.

Maybe I'm an idiot but my curiosity got the best of me and I clicked the link. The photos just look like abstract modern art, although their perceptual hash may match that of known CSAM, I doubt that anyone who clicked the link will get into legal trouble even if Google flags that folder by detecting a perceptual hash match, as they will likely use real people to verify before taking legal action.

Google has been recently focused on cultivating the image that they care about user privacy. The last thing they want to do is call the cops on a bunch of HN users for looking at some abstract swirly pics.

Yeah, I installed tor-browser later and checked the link
