You do understand that what you're asking for is literally impossible, not just "easier said than done"? Blocking bots until proven human is exactly the same as allowing humans until proven bot. They already are forcing "bots" to prove they're human, to the best of their abilities. At some point their measures dictate that traffic from VPN = bot, until that "bot" can prove otherwise. If you're blocking whatever mechanisms they use to identify "human" then it shouldn't be a surprise that they can't differentiate you. Their only interface is whatever traffic happens between you and them, not any intention or motivation behind your actions. They have a negative interest in blocking people from accessing anything, since pageviews = ad views = dollars. The only time they have an incentive to block anyone is for click fraud, or for any similar reputational damage from a person / bot / IP.
