You should read spam and fake blogs, another problem I’ve been seeing a lot lately is entire blogs being scraped and their content being re-published with ads on it. Structured formats like RSS make this easier than before. The dark side to the numbers all the blog search engines have been toting is that a LARGE percentage of these are fake blogs, so much so that I currently block over 80% of all incoming pings to Ping-O-Matic as obvious spam. This has been a huge resource burden as well. We have around 2 million legit pings per day, do the math.
