There used to be a site called 4u-beautyimg.com which was supposedly a "social image bookmarking site" but really it was basically just a ton of pictures of beautiful Japanese women, mostly gravure idols and occasional nudes. I'm pretty sure everything was posted by one Japanese dev who just really liked women. It was a simple site, a little bit sus/spammy, but I miss it.
Do you guys know any other sites that let you just mindlessly scroll through semi-nsfw pictures of beautiful women? Besides the obvious (4chan, tumblr, boorus). Maybe I should just go find some good torrents and amass my own collection.
