QAnon Is Trying to Trick Facebook’s Meme-Reading AI | WIRED

It’s hard to create ironclad content-moderation systems in part because it’s difficult to map out what they should accomplish in the first place. Anish Athalye, a PhD student at MIT who has studied attacks against AI, says it’s difficult to account for every type of behavior a system should protect against, or even how that behavior manifests itself. Fake accounts might behave like real ones, and denouncing hate speech can look like hate speech itself. It’s not just the challenge of making the AI work, Athalye says. “We don't even know what the specification is. We don't even know the definition of what we're trying to build."
