Allow me to disagree. Best repositories are pixiv, nijie.info, artist blogs, etc. 99% of content comes from there. (example:http://ameblo.jp/santa1500/imagelist-201510.html) The pics there are not even indexed by google images. I need to rip the full res pics and upload the image set on sadpanda (ameblo won't let you unless you use the chromium dev tools). I'm actually the guy who scanned and uploaded FW01 quite recently on perfect dark and have lots more underground stuff that is unscanned. Shops like mandarake, rakuten, amazon.jp, auctions.yahoo.co.jp, k-books etc, have good rare unscanned doujin/tankoubon/daki covers/garage kits/PVC ero-figures, shikishi with autographs etc. Of course most are very expensive due to the rarity factor. Top 3 places for otaku goods in Tokyo are Shibuya, akiba, nakano. Many good stores but kinda hard to locate since many are placed in backstreets and are pretty small.
To summarize, ~50% of content on lolibooru weren't even trulolis (prepubescent), most had budding breasts and incorrect anatomy. Most were actually of teen age. (inb4 teens are lolis). Don't confuse generic moeshit illust with truloli. I know there is lot of censorship going on in japan recently, the gov/comiket, toranoana etc actually forces artists to make lolis look like old hags (olympics?), otherwise they won't sell it. Shit like the new LO issues and nutaku is trying to brainwash people to become non-lolicons. There are discussions on various japanese chans about this problem. If needed we will create an anonymous marketplace (a cipherspace market / Tor HS, openbazaar etc) for artists to sell their content without any kind of censorship. The artists be paid using cryptocurrencies, and the content will be downloaded in digital form. There is actually a fork of bitcoin called lolicoin!
I will do everything in my ability to protect tru 2D lolies.
Fucking lolieromangaka need to learn how to draw loli correctly, especially artists like henreader, his new stuff is kuso-tier. That pic you posted is a good example of correct loli anatomy. IMO best loli artists are moku ujiie, sasahara yuuki, misao, inuboshi, ootsuka reika, fuyuno mikan, himeno mikan (their older stuff), Equal/イコール, sakurafubuki nel, Kouguchi Moto, tamanin, takamichi, higashiyama shou, sol-fa-soft, tofu-soft, iris-soft, cura, ほっけうるふ/SuperFlatLolinitron, inuarasi, koyomisa, shiawase manjuu, inuburo, lasto, sakurabe notosu, and many, many, many more i can't recall right now.
Pic is some stuff from my room. Kinda unrelated to this thread but i believe i own the best loli goods in the entire world. I'm also practicing on a cintiq 27QHDT so i can become a decent loli artist and provide myself and the world with 2D sweet seminated loli cunny of excellent quality. I actually have a fetish, NEET cyberpunk hacker lolis on drugs, i will draw alot of that, maybe even make a manga or write a light novel.
That is all for now, im pretty tired because i IV'ed alot of eticyclidone (2-Oxo-PCE) and flubromazolam and feel really sleepy.
