While checking on my site report for google adsense, I came upon this mysterious “cloudflare.works” domain coming up in the referral traffic.
The site was only showing up as a couple hits a month. Upon attempting to visit any of the displayed subdomains, I’m presented with a message:
This may not be the page you're expecting (request failed security checks).
My guess is these referrals are being generated from automated or manual reviews of websites by developers using cloudflare’s new app platform.
