A friend told me to mention this here... There are above the radar and below the radar ad buys. If you buy like 50 off topic links from a well known blog network expect those links to not count for much Weblogs Inc recently places like 50 casino ads on their blog network. The funny thing is that they have a gambling blog (with AdSense ads), but most of the casino ads are on their other blogs. http://www.threadwatch.org/node/6312
