Just came across 3 of the top 10 websites for a particular category (all owned by the same person) that when clicked, automatically redirects to an affiliate website that is paying by clicks, not sales.
Googlebot obviously can't detect this so you would have thought that if you report a specific site, it would be banned. Problem is Google don't like manually removing sites. It's Catch 22. Not one site that i've reported over the last few months has been removed.
I'll still keep plugging away reporting sites who do this though. I suggest you do the same.
