This said, most expert advisors programs aren't really functional, need a human supervision. IMHO the devs make more money from the sales/subscriptions of their software than running their "money making machines". After all, if your "completely automated money machine" actually works, why would you bother in paying marketing, DRM schemes to have other people using it?
Cloudflare knows almost everything done from your IP address because they're used by the majority of websites. And some websites are using a cloudflare signed TLS certificate so if cloudflare wants, can see the content of the communication instead of an encrypted package
So they know if you have a human behavior (visiting many different websites at human speed and having rests during sleeping time) or if you have a bot behavior (sending millions of requests to the same endpoint at superhuman speeds)
