1500chan, nicknamed Caravela,¹⁾ is a Brazilian Portuguese bulletin board co-founded by former BRchan staff “N.” and “R.”²⁾ around April 28, 2013. The website used to be a niche website for old users, but recently exploded after 55chan and SFChan migrated to 1500chan in 2020.

With BRchan's death on April 19, 2013, former BRchan moderator “N.” set up HUEchan at “huechan.net” with Kusaba X on April 28, 2013.³⁾ The name sucked, so they renamed to 1500chan at “1500chan.org” on May 5, 2013.⁴⁾ 1500chan eventually switched to Vichan on August 13, 2018, but couldn't figure out how to add themes or have more than five boards until “Eggman” helped after the 73chan merger on October 30, 2019.

In 2020, the announcement of 55chan's imminent closure led to SFChan contacting 1500chan about a merge, so a joint announcement was made on October 5, 2020, sending them to a /jp/ board.⁵⁾ This small move had unexpectedly became an avalanche, so 1500chan capitalized by adding several 55chan-derived trial boards on January 5, 2021, right before 55chan formally shut down on January 15, 2021.

Since it became 55chan's true successor, “N.” declared 1500chan was “pro-Bolsonaro” on October 28, 2021, directly feeding into the far-right cesspool.⁶⁾⁷⁾ Then on June 4, 2022, 1500chan gained national attention for their “pro-Bolsonaro fake news”,⁸⁾ so they rushed to set up a fake 404 page to deter readers, then Lula beat Bolsonaro. The fake 404 page and mandatory /b/ redirect wasn't actually removed until 2025.

• The former 1500chan mascot was a cockatiel (calopsita) since /b/ had many cockatiel threads and 1500chan started a “Bird Culture” (/ave/) trial board as a joke,⁹⁾ but it only lasted five months.
• On their fake 404 page, where you had to write “Eu sei usar acentuação e pontuação.”, the math problem, 7(2x-3)-4(x+5) = 8(x-1)+3, would generate a graph whose answer is x = 18.
• For some reason, “N.” loves pinned threads and making his presence known, despite the anonymous nature of the website, so 1500chan has also gained the nickname of “Pinadochan” as a result.
• There hasn't been a way to archive 1500chan since 2020, as they use Cloudflare and had that fake 404 page from 2022–2025, so we're just left with a bunch of screenshots.
