After President Joe Biden’s April decision to withdraw U.S. troops from Afghanistan, the Taliban made stunning battlefield advances — and nearly the whole nation is now under the insurgents’ control.A Facebook spokesperson told CNBC: “The Taliban is sanctioned as a terrorist organization under U.S. law and we have banned them from our services under our Dangerous Organization policies.”Facebook said this means it will remove accounts that are maintained by or on behalf of the Taliban, as well as those that praise, support and represent them.”We also have a dedicated team of Afghanistan experts, who are native Dari and Pashto speakers and have knowledge of local context, helping to identify and alert us to emerging issues on the platform,” the Facebook spokesperson said. Facebook said it does not decide whether it should recognize national governments. Instead, it follows the “authority of the international community.”WhatsApp dilemma?Reports suggest that the Taliban is still using WhatsApp to communicate. The chat platform is end-to-end encrypted, meaning Facebook cannot see what people are sharing on it.”As a private messaging service, we do not have access to the contents of people’s personal chats however, if we become aware that a sanctioned individual or organization may have a presence on WhatsApp we take action,” a WhatsApp spokesperson reportedly told Vice on Monday.A Facebook spokesperson told CNBC that WhatsApp uses AI software to evaluate non-encrypted group information including names, profile photos, and group descriptions to meet legal obligations.Alphabet-owned YouTube said its Community Guidelines apply equally to everyone, and that it enforces its policies against the content and the context in which it’s presented. The company said it allows content that provides sufficient educational, documentary, scientific and artistic context.Twitter and TikTok did not immediately respond to a CNBC request for comment.
