There is a way they block access to humans with CAPTCHA. Even to government sites that should not be obstructed. Whatever X uses has impossible CAPTCHAs that don’t add up. The Google CAPTCHAs go in an endless series that will keep you solving for hours. It doesn’t matter if you are using VPN or tor. Never seen the one from cloudflare fail. But I think CAPTCHA has become another NSA chokepoint that needs to be open sourced.
