There isn't a single solution to be had because there isn't a single way you interact with strangers online. Verifying identity is necessarily completely different if you're sending someone an item in exchange for money, or looking to date them for a while, or going into long-term business with them, or maybe just having a discussion where you want to validate that they work where they claim. We don't need blanket verification of people's identities online. If a bot is posting on a service and is indistinguishable from an interesting human, why shouldn't it stay? "On the internet, nobody knows you're a dog" used to be the Web 1.0 motto.
