December 29 - Following a massive flood of real-life child pornography, /l/ (Lolikon) is temporarily deleted.
April 20 - 4chan administrators are forced to temporarily shut down img.4chan.org after a thread containing four uncensored images of child pornography became stuck on the front page for over an hour (during which nobody could post) and could not be deleted due to MySQL problems. Rather than getting v&, the plug was pulled on img.4chan.org and was restored around 12-15 hours later. During the downtime, since 7chan was down as well, a massive amount of /b/tards flocked to 420chan, thus ruining 420chan's most special day, 4/20.
August 13 - Naruto Day: /a/’s elitism finally goes too far when they dox a 4chan mod (RapeApe) who posted on /q/ telling them to stop complaining about naruto threads. moot retaliates changing the board name to /a/ - "N/a/RUTO CONFIRMED BEST ANIME CHINESE CARTOON OF ALL TIME", with the subtitle "BELIEVE IT (also dubs are better than subs)", embedding a remix of "believe it", changing the posting form and stickying a bunch of Naruto threads. /a/ goes berserk and begins spamming CP and guro, forcing the mods to take it down.
December 22 - /b/ has a successful raid for the first time in ages. An anon finds a network of school sites have the default username and passwords. He proceeds to post them on /b/ to which a group of anons deface the site with the usual: porn, and the words "nigger" and "faggot" as well as a link to a narcotic honey-pot. CP had also been reported to have been posted.
January 5 - Site goes on an outage from 01:32 - 13:10 (EST) due to MySQL error. Boards are semi-functional, as in the board pages are frozen, but you can open threads and post, and also make new threads. People begin to make CP threads during this time.
October 2 - Donald and Melania Trump confirm that they have the coronavirus. /pol/ freaks the fuck out and
also gets a sticky. Meanwhile, bunkerchan.xyz (the remainder of 8chan's /leftypol/) considers it wise to raid /pol/ with 'Chudjak', a Wojak of the guy who did the El Paso shooting, which they proclaim a caricature of the typical /pol/ user. Pissing into an ocean of piss leads to you getting pissed back at, and Bunkerchan proceeds to be raided overnight by a few shitposters, a spambot, gore, lolicon, cp and the subversion of the meme they were trying to spam. It gets too much for Bunkerchan mods, and they lock the board. It eventually turns out there's no evidence that the spam started on Bunkerchan, and it was probably actually done by /qa/ soyposters and random trolls who joined in. Whoops!
