“There hasn't been any new content in at least a year, and the constant off-topic circlejerking and porn posting has been a continuing problem for moderation. 4chan isn't meant to be a chatroom where a dozen or so people who all know each other can blog about their daily lives”
– Anonymous ## Manager¹⁾

4chan is a large bulletin board website, a Futaba Channel-inspired clone, founded by Christopher Poole on October 1, 2003.²⁾³⁾ In 2015, it was acquired by Hiroyuki Nishimura for $8 million,⁴⁾⁵⁾ but he has mostly been hands-off, so “RapeApe” has effectively been running the show.⁶⁾

The website once aspired to be Futaba Channel's English-language analogue,⁷⁾ but ended up with 2channel's stupidity with images, and it wasn't even the Western internet's first introduction to 'anonymity'.⁸⁾ However, it was certainly notable for housing anonymity at a large scale at one point, with inconsistent moderators trying to take a 'relaxed' approach, at the cost of the community growing hostile and contrarian over time.

While the 'anonymity' stands out, the 'notoriety' is the real reason we're still talking about it. Ever since its shift towards low-effort ragebait (e.g. 'culture war', Reddit/Twitter screenshot threads, political bait, etc.), it shouldn't be a shock that 4chan hasn't been known for its 'creativity' in ages, especially as users grow skeptical of inorganic discussions, and no amount of 'autosage' will hide that.

In 2001, the Something Awful forums reluctantly creates their anime subforum, ADTRW, which influences the creation of Raspberry Heaven and its DC++ hub. At some point, Futaba Channel (“2chan”) became a hot topic, despite later barring non-Japanese IPs. On September 29, 2003, Poole initially registers the “4chan.net” domain,⁹⁾ supposedly intending for it to be a email address¹⁰⁾ as a bored, hormonial teenager.¹¹⁾

“A “cool” anime board would be great, but look at the posts in this thread complaining about an abundance of retards now using the site. Do you see how adding this board would probably result in complete failure?”
– Christopher Poole¹²⁾

4chan sets up their first imageboard on October 1, 2003,¹³⁾ angering a *certain* World2ch user,^14)15)16) and it quickly escaped the Raspberry Heaven in-group¹⁷⁾ after a week¹⁸⁾ or month.¹⁹⁾ Much of its early history²⁰⁾ is otherwise unremarkable board additions and bug fixes. Some people wanted to take 4chan down,²¹⁾ which led to GoDaddy releasing the “4chan.net” domain on February 11, 2004.²²⁾²³⁾

The website then moved to “4chan.org”,²⁴⁾ but 5chan allegedly had their PayPal account frozen,²⁵⁾ forcing 4chan into a two-month hiatus from June 20, 2004²⁶⁾²⁷⁾ to August 11, 2004.^28)29)30) Shortly after, they had a panel at Anime USA 2004,³¹⁾ and offloaded certain boards to not4chan. In 2005, they held another panel at Otakon 2005,³²⁾ then boldly banked on a one-time, month-long donation drive to stay afloat.³³⁾³⁴⁾

In 2006, the ban system was reworked,³⁵⁾ a third panel was held at Otakon 2006,³⁶⁾ but then came the whole Anonymous concept, the '/b/-day' fiasco, and terrorist threats, so the fourth panel at Otakon 2007³⁷⁾³⁸⁾ was the last for a while.³⁹⁾⁴⁰⁾ Much of the 'late 2000s chaos' was romanticized to death.^41)42)43)44) This decade would close with new 'sans-serif' themes⁴⁵⁾ and ReCAPTCHA.⁴⁶⁾

“However these days, many posters use this precious gift as a license to say and do whatever they'd like, often to the detriment of the board.”
– Christopher Poole⁴⁷⁾

The early 2010s were a more experimental period. While “News” (/new/) and “Robot9000” (/r9k/) were initially removed,⁴⁸⁾ hassling DeGrippo about Encyclopedia Dramatica's removal⁴⁹⁾ made Poole's hypocrisy clear,⁵⁰⁾ leading to its undoing with a rebranded “Politically Incorrect” (/pol/) board on October 23, 2011^51)52)53) before a certain meeting.⁵⁴⁾ This was criticized to death for facilitating an 'alt-right' counterculture.⁵⁵⁾⁵⁶⁾

In 2012, the '4chan Pass' is introduced,⁵⁷⁾ then came the catalog.neet.tv-inspired catalog⁵⁸⁾ with an inline extension.⁵⁹⁾ In 2013, a fifth '10th anniversary' panel is held at Anime Weekend Atlanta 2013,⁶⁰⁾⁶¹⁾ then 'sage' became invisble.⁶²⁾ In 2014, the 4chan Blog moves from Blogspot to Tumblr,⁶³⁾ they added in WebM support,⁶⁴⁾ and the Blotter returns as “Rapidshares” (/rs/) and World4ch shutter.⁶⁵⁾

However, 4chan in late 2014 found itself entangled with Anon-IB's Fappening in August, the beginnings of GamerGate in September which led to staff fatigue and 8chan,⁶⁶⁾ then 4chan controversially asked staff to provide real-world IDs and sign NDA contracts,⁶⁷⁾ despite the website's ethos of anonymity.⁶⁸⁾ On January 15, 2015, the website's fate was put in limbo as Poole announced his intent to step down.⁶⁹⁾

“I think people, again, as I pointed out in that sticky, have kinda chosen to kinda conflate or willingly misinterpret being an advocate for anonymity as being an advocate for free speech.”
– Christopher Poole⁷⁰⁾

“Thanks. We have to get more free speech on 4chan than TV.”
– Hiroyuki Nishimura⁷¹⁾

Then on September 21, 2015, it was revealed that 2channel founder Hiroyuki Nishimura, whom Poole met at 2011 SXSW,⁷²⁾ would take over 4chan in an $8 million sale,⁷³⁾ following a recent theft.⁷⁴⁾⁷⁵⁾ Nishimura's 'free speech' idealism was clear,^76)77)78) but then came a weird donation scheme,^{79)80)81)82)83)} before deciding to be 'hands-off' with 4chan.⁸⁴⁾ In this power vacuum, “RapeApe” takes over.⁸⁵⁾

By this point, 4chan effectively lost its 'neutrality', so longtime sponsor J-List pulls out,⁸⁶⁾ and 4chan goes through a string of questionable advertisers, even offloading the work-safe boards to “4channel.org” from November 17, 2018⁸⁷⁾ to December 18, 2023. During this, there were significant board lineup changes, a new slider CAPTCHA on July 5, 2021,⁸⁸⁾ and Good Smile Company sells its stake around July 2022.⁸⁹⁾

In 2024, they began testing email verification,⁹⁰⁾ which then spread to every board,⁹¹⁾ so people that refused were forced to deal with a 10-minute timer. Then on April 14, 2025, 4chan is hacked by a British⁹²⁾ Soyjak Party user through a Ghostscript exploit, leaking the source code, the “Janitor & Moderator Discussion” (/j/) board, the staff list,⁹³⁾ and ultimately exposed their decade-old setup.⁹⁴⁾

“No shady billionaire is financing us. It is a constant struggle to keep this place going.”
– RapeApe⁹⁵⁾

Following the hack, 4chan is restored on April 25, 2025, with PDF uploads and “Flash” (/f/) disabled, but their non-email timer was cut down to a 2-minute timer and most of the staff had resigned. By June 16, 2025, the 'bans' page became vague,⁹⁶⁾ therefore less transparent. 4chan is then given an OSA-related⁹⁷⁾ fine by the British Ofcom,⁹⁸⁾⁹⁹⁾ so 4chan and Kiwi Farms took them to court on August 27, 2025.^100)101)

Later that year, 4chan holds its longest recruitment drive in September, switches to a slider+circle CAPTCHA around October, then came maintenance¹⁰²⁾ and a three-question quiz CAPTCHA on December 12, 2025.

Every now and then, 4chan holds a recruitment drive to help out with their content moderation. If you are considering, be aware that the website has a company behind it, you will not be paid despite the managers making >$4,400/mo,¹¹²⁾ you are expected to 'de-anonymize' on camera and sign an NDA contract,¹¹³⁾ and you will obviously have to moderate 4chan. Poole *did* describe it as “the shittiest job ever”.¹¹⁴⁾

In the 2025 hack, it was discovered that the captcha.php file had a list of whitelist countries,¹⁴³⁾ namely from North America, Europe, Asia, and Oceania. This section simply converts said list of ISO 3166-1 alpha-2 codes into a more accessible format, removing the guesswork for people who aren't nerds. Of course, do note that the code/whitelist may have changed since then, like Guernsey.

• 4chan used to call itself 'Yotsuba Channel' (よつばちゃんねる),¹⁴⁴⁾ which is why they initially borrowed 'Yotsuba Koiwai' (小岩井よつば) from Yotsuba&! as their mascot, sometimes called '404 Girl'.
