What value does any of this have to anyone at all except him? What an absurdly stupid waste of time. They pay for traffic which in my book makes it illegitimate because it isn't genuinely interested people, and expects it to what, be people paid to click around instead of machines spun up to click around? How is that any less stupid?!
I don't think it's that clear that paid traffic means illegitimate: you can pay for ads on Search and expect it to be human traffic that is interested for example.
