I picked up a new client whose site has a WordPress blog in a subdirectory. He told me how active his blog was and he is very pleased with it. He was surprised when I pointed out that with over 1400 comments, only 5 are legitimate. All the rest are spam comments.
I still find it hard to believe that people don't don't suspect that something strange is going on when they have over 1000 comments praising the quality of their blog or its theme.
