Tuesday afternoon, Facebook took down the page that purchased Goldy’s advertisement under its authenticity policy, which says users can’t misrepresent their identity on the platform.

Goldy isn’t the only banned Facebook presence with ads in her name. A page called “Royal Canadian Infidel,” which has since been removed, shared content that was similar to that of the banned Canadian Infidels on Facebook. It also ran an advertisement Tuesday selling T-shirts for the group.

The ability of Facebook and other platforms to effectively remove offensive, hateful, or graphic content came into question last month, when livestreamed video of a mass shooting in Christchurch, New Zealand, was still available hours after Facebook and other major social media platforms claimed to have removed it.

This time, the social media giant has shown it is unable to effectively enforce bans it chose to implement on its own schedule.

“Individuals and organizations who spread hate, attack, or call for the exclusion of others on the basis of who they are have no place our services,” a Facebook spokesperson said in an emailed statement. “We will continue to review individuals, Pages, groups and content against our Community Standards, and take action in line with our policies. We take this very seriously and our work against organized hate is on-going.”

Facebook said its ban extends beyond the groups named on Monday to all affiliates, including linked pages and groups, and it will remove content that expresses support or praise for them. The platform said it will be investing in artificial intelligence to proactively remove content that violates its policies before it is reported.

A page in the name of the Canadian Nationalist Front, which was also banned Monday, popped up hours later posting links to news stories about its being banned. The new page, which was later taken down, linked to the group’s website and listed the group’s leader, Kevin Goudreau, as a contact.

Evan Balgord, the executive director of the Canadian Anti-Hate Network, said he wasn’t surprised Goudreau was able to get back online so fast.

“The content he posts ... was regularly successfully reported and removed before this new policy was in place. He always comes back. Facebook will have to keep on top of it,” Balgord said.

BuzzFeed News and the Toronto Star found 10 pages, groups, and Instagram accounts promoting Canadian Infidels’ content — after the ban was announced — that were not caught by Facebook. There appeared to be coordinated activity between two of the pages, which promoted the same Yellow Vest event and published the same memes at roughly the same time.

“Facebook promised to remove affiliated pages, and we’re waiting for them to do so in a comprehensive manner,” Balgord siad. “Facebook has a legal responsibility under the Canadian Human Rights Act to proactively remove them.”

Balgord said several other prominent white nationalist groups, including Atalante Québec and Fédération des Québécois de Souche, were not part of Facebook’s ban, and still remain on the platform.

“To the best of my knowledge they didn’t consult with any Canadian experts,” Balgord said. “If they did, we would have provided a better list.”

Researchers have noted that hate, racism, and anti-Muslim content are out of control on Facebook. Megan Squire, an Elon University computer science professor who researches online extremism, found white nationalist, conspiratorial, and anti-Muslim groups have built up a large, interconnected network on the platform.

“They know that by using the social media platforms they can spread their message, and they figured out how to do that,” she previously told BuzzFeed News.
