The author said it himself, he could have just put Cloudfront in front of Pages and parsed the access logs there. The referrer and user-agent, which are sent by the browser, are in the request headers. There would be no need for JS or an image if the website owner just changed their setup.

How do you deal with this sort of tracking?

What do you mean? I think using CloudFront is not accurate enough if you use caching.

I guess I mean overall "you can't stop owners from analyzing their access logs" and not just related to Cloudfront.

They've got an enterprise logging tool that'll give you all the info needed for this sort of tracking. https://support.cloudflare.com/hc/en-us/articles/216672448-C...

This is "Front", the Amazon offering, not "Flare" (side note: logging via Cloudflare Workers is cheap and possible)
