I have a similar issue. I see cloudflare checkboxes all the time. Google makes me fill out captchas all the time. Sometimes it decides I can’t search, sometimes cloudflare doesnt let me past the checkbox.

I’ve checked my network. I’ve monitored egress traffic. There is no residential proxy. I’m not on a VPN. If anything, services should be able to track me entirely by my home IP that doesn’t change that often.

My best guess is that I’ve committed the crime of not allowing third party cookies? Or maybe the crime of not being logged into a Google account 24/7. It’s not browser or device specific. My iPhone is just as likely to fail the cloudflare checkbox as my desktop with Firefox + uBlock.

I've committed the extreme crime of running no JS and clean cache of cookies. Plus, something as simple as containerizing work/play/research reading, into different browsers, has provoked the Eye of Google to be cast on me

I haven't seen a YT ad in years while in lurk-only mode (no login), which is nice, but I also see cloudflare everywhere , which is not great.

One of the nicer things about LLMs, is that they arrived just in time to erase my dependency in search.
