After shootings, tech companies urged to pull plug on 8chan
Online message board has become hotbed for extremist white content
Critics pressed Twitter and other tech companies to shun online message board 8chan on Monday, after it was used by a mass shooter to announce an attack for the third time this year.
Employing the hashtag #untwitter8chan, users urged Twitter CEO Jack Dorsey to boot 8chan off the platform.
8chan, which in its verified Twitter profile describes its location as "The Darkest Reaches of the Internet," has become a hotbed for white extremist content.
Twitter was "proactively removing content that violates our policies and will be engaged with law enforcement, as appropriate," company spokesman Ian Plunkett said. He declined to comment on 8chan's account.
The gunman who killed 22 people at a Walmart store in El Paso, Texas on Saturday is believed to have posted a four-page statement on 8chan before his attack, calling it a "response to the Hispanic invasion of Texas."
The site was previously used this year by the shooters who attacked two mosques in Christchurch, New Zealand and a synagogue in Poway, California.
8chan, which is run by an American living in the Philippines, was struggling to stay online on Monday after U.S. cyber security firm Cloudflare terminated it as a customer in response to the Texas shooting.
It quickly found a new home with Epik, a Seattle-based company which last year welcomed neo-Nazi site the Daily Stormer and "free-speech" site Gab. Both lost service providers for similar reasons: the Daily Stormer after users helped organize a rally in Virginia that turned violent, Gab after the Pittsburg synagogue shooter used it to express anti-Semitic views.
"Our services fill the ever-growing need for a neutral service provider that will not arbitrarily terminate accounts based on social or political pressure," Epik CEO Rob Monster wrote in a statement.
But within hours, after being alerted to the 8chan connection by former Facebook chief security officer Alex Stamos, Epik's own web infrastructure provider Voxility dropped it as a customer.
At the time of writing, 8chan's site appeared to be down.
Stamos on Sunday reiterated his call for "responsible tech companies" to blockade 8chan by not allowing links to the site, citing its use as a recruitment tool.
8chan did not appear to have any official accounts on Facebook, although links to the site were available there. A Facebook spokeswoman said direct links to the shooter's manifesto were being blocked.
A Google search did not return any direct links to the website, but it did return 8chan's official Twitter account, which links to its homepage.
Cindy Cohn, executive director of digital rights group the Electronic Frontier Foundation, urged caution in looking to tech platforms and services to address mass violence.
"Because these services may determine whether one can use the internet at all, those companies providing them must use their power on only very rare occasions, if at all," she said.
