( It's sufficiently basic that a bot I wrote happily grabs the challenge, solves it, submits it, gets the cookie, re-accesses with the cookie, and grabs the data, then re-uses that cookie until the site decides the cookie expired and it starts over again. I'll have to see how it fares with bitmain's site. )
You're sending vastly more information to a site about your browser just accessing a page in the first place.
Why do i need to see the message that the site is checking my browser for DDOS?
I certainly do not need to see that snippet-it should be done in the background.
Is this your first exposure to cloudfare? This is the way it works dude.
