... or individual browsers taking small steps to preserve their privacy.
I obviously don't know how many Cloudflared sites I visit that don't pop up the nag. And Cloudflare's nag is certainly nicer than Google's more pervasive help-us-build-a-T-800 or Akamai's "just get lost". But that mode seemingly activates on light browsing just because it's coming from a slightly-less-trackable VPS address (non-shared), and that is a problem.
I'd just like to mention that this service saved me once. I have a small low-end box and one of the sites I hosted (that belonged to a YouTube personality) was DDOS'ed for a while, it kept taking the server down. A combination of crafty server configuration and enabling the "Under Attack" mode helped me deal with it.
