The idea is not to make people pay 5 cents to see a website. Instead replacing captchas with a toll for about how much it would cost to have a human solve the captcha for you.
This will only work with mechanisms that let you pay like 0.05 cents. Should be enough to deter bots that practically run for free these days.
Too bad any intermediary will want 0.30 dollars per transaction for the 0.05 cents :)
* note that the word just does an obscene amount of lifting in that sentence.
This is alosing idea out of the gate.
