Thats why I said proof of work that is used to mine a cryptocurrency to pay the bills of websites that serve information.

As long as the website gets paid more than the cost of serving the pages, it does not matter if a human or a bot did the POW.

Securing signup forms is another issue. Maybe related. But not what I was referring to.

Very good point, I missed the point that the PoW is paying the publisher. I will have to dig into this, this is a pretty nice idea.
