So, even after removing the links to my torrent files, Google's AdSense team still says I'm violating their policies. Unfortunately, since you can never talk to a living person at Google, I don't know exactly what I'm doing wrong.
Therefore, this site is now ad-free. Financially, it doesn't make a big difference to me; I was only making about $6 a month in ad revenue, so it's not like I'm missing the money.
However, I would simply ask that, if you downloaded the book for free and find it useful, please consider buying an electronic copy, or two, or three. :) Since I don't have a donations button, and can't have ads on the site, book purchases are the only way I make any money for my effort.
However, I will continue to offer the book for free for those unwilling or uninterested in purchasing it. Please don't feel obligated in giving me money. I wrote the book for the benefit of others and the money is simply a nice thing to have.
Again, thank you for your interest and, if you buy a copy, I greatly appreciate it.
