For better or for worse, CF's fingerprinting and traffic filtering is a lot more in-depth than just IP trend analysis. Kind of by necessity, exactly because of what you mention. So I'd think that's not as big a worry per se.

Yet here I am drowning in captchas every once in a while, so it's quite a big worry for me.

Maybe I just have to disable all ad blockers and Safari tracking prevention? Or I guess I could send a link to a scan of my photo ID in a custom request header like X-Please-Cloudflare-May-I-Use-Your-Open-Web?

I think I was sufficiently clear that I was specifically talking about CGNAT-caused IP address tainting being an unreasonably emphasized worry, not the worry about their detections overall misfiring. Though I certainly don't hear much about people having issues with it (but then anecdotes are anecdotal).

Sounds good, have you tried?

Not sure what's the point of these comically asinine rhetoricals.
