If you spend an hour or so systematically googling things you have never shown any online interest in before, Google will make you prove you are not a robot. I learned that when I went through 50 or so blogs of the kind I rarely read myself, googling the same two phrases within each site – for like two hours. Suddenly I had to type in one of those prove-you-are-human codes because of my “unusual search patterns”.
