Not4chan was a short-lived bulletin board that was run by the Raspberry Heaven member “Saber” and once had ties to 4chan.¹⁾ The original ran from November 5, 2004, then vanished around July 2006, either due to the owners losing interest or in fear of Statesian legislation.

Due to legal threats, 4chan removed the “Lolikon” (/l/) and “Shota/Male” (/sm/) boards on October 31, 2004, so not4chan was set up at “not4chan.org” on November 5, 2004. Shortly after, “Guro” (/g/) was removed on November 15, 2004, but it curiously was never picked up by not4chan, presumably due to Gurochan doing it for them, then 4chan eventually replaced it with a “Technology” (/g/) board on January 19, 2004.

There isn't much known about not4chan, aside from its strict moderation and constant morality debates that surrounded it.²⁾³⁾ The only evidence it existed was a 4chan announcement on “Straight Shota” (/ss/) being added on April 7, 2006⁴⁾ and several World4ch threads.⁵⁾⁶⁾⁷⁾ Then, it disappeared around July 2006,^8)9)10)11) either due to a lack of interest¹²⁾ or fear of the Adam Walsh Act.¹³⁾

Most evidence of these boards existing can usually be found on Google in old forum posts or the board was listed as a source in old image gallery post. Oddly enough, no archives of the boards or threads exist.

• /l/ - Lolikon
• /rl/ - Request/Loli¹⁴⁾¹⁵⁾
• /sm/ - Shota/Male
• /ss/ - Straight Shota
• /tl/ - Torrents/Loli

An unofficial successor would emerge at “not4chan.us” on August 30, 2006, established by “narunet” and ran on Wakaba.¹⁶⁾ It struggled, died, and had three boards before moving.¹⁷⁾ They would later redirect to “not4chanserver.org”, established by “Lime Coke” on January 1, 2007 and ran on Thorn,¹⁸⁾ but this didn't last long either and the website had presumably died around February 25, 2007.

Several months later, there was “notfourchan.net”, re-established by “narunet” and “crazymonkey” on July 6, 2007,¹⁹⁾ and originally ran on Serissa. For some reason, this iteration quickly became a J-List affiliate.²⁰⁾ After a few years, they switched to Kusaba X on February 19, 2010,²¹⁾ then they vanished around December 1, 2011 as the host dropped them.²²⁾ They just never learn.²³⁾

• There was once the “not4chan Grab Extension”, a Firefox extension²⁴⁾ for downloading images, developed by “Random Translator” who released the final version, v1.14, on July 11, 2008. It was later forked into 4chan Grab, but the extension is now over a decade old.
• Recently, the original “not4chan.org” domain was recently picked up on December 13, 2023, but it is mostly being used as an archive for 4chan and 789chan of the /cwc/–/cow/ lineage.
