I have an amusing story about RedZee from last week.
A rep calls and she tells me how great RZ is and how I need to be in the top position. She then mentions that it is the world's only "family friendly" search engine with no illicit content etc. While she is telling me this, I search "hentai" which animated japanese porn, basically. I find tons of links and even Amazon.com advertising on RedZee or at least an affiliate. I crack up and tell her and she pretends to be very startled.
Needless to say, I'm not advertising, nor did I get any finder's fee.
