I'm not actively trying to avoid detection (e.g. VPN, Tor, etc.). Another user mentioned Firefox's privacy.resistFingerprinting might be the issue, but I don't have that enabled. Maybe there's something else in Firefox that is avoiding (A), and I'm willing to open a Firefox bug report to investigate that, but the core issue here is CloudFlare blocks without any diagnostic information and its community support forum didn't engage. This HN post has caused some amount of engagement from CloudFlare and hopefully it'll be fixed.
