I don't understand why an actor needs to be tested and marked as secure on first interaction. There must be signals so that the server could initially trust an actor in some case. For example, why can't the server trust a never before seen IP attempting to sign into an account that hasn't been experiencing incorrect password attempts? Is Cloudflare just a case of a one size fit all solution?

the problem is it's too easy to make a botnet attack a sure by having each computer try a password for a unique account once per day. this wouls let you get a few million chances per day or website at guessing user passwords without detection.

In theory, this could be countered by moving to one wrong password attempt per IP over any web site protected by Cloudflare. I have a better understanding of the threat and there might be other drawbacks.
