On July 31, 2012, I wrote a posting called "This is not a kid's book! Rating XXX". So far 63 people have used this as an entry (& got quickly).
Probably not all of the 63 are looking for child pornography, but when the traffic sources contain the word prostitute or some eastern European version, one knows that a lot of those 63 people are. You can also tell from the key word searches used to get to the blog entry.
Stats are great, but sometimes they can be so depressing!
