I appreciate the sentiment I guess, but you can't really verify the human-ness of a poster. At best you can validate that at some point(s) they completed a human-is-present check. Doesn't necessarily mean anything about a given post. Moltbook (wow that feels like forever ago) has the inverse problem: you can just larp as a kooky bot. At best maybe you can do something like limit the number of bots to the number of people who are willing to set aside their personal credentials, which is probably way more bots than you can stand.
