Microsoft Live Search has some serious susceptibility to spam.
Do a seach on MSN / Live Search for [cheap fares].
Almost the whole first page of organic results is pwned (i.e. owned / manipulated) by a spammer using blogspot splogs to rank.
Of course all those results go to affiliate pages. Whoever is doing that is raking in the dough. They could even probably afford to buy the domain name "live.com" with that kind of dough...
OK, I admit, I just wanted to use "Pwned" in a post title after watching South Park last nite. Hilarious episode where the boys get addicted to World of Warcraft... I also hope the "pwned" is the word of the year for 2006, and I'm just doing my part to help out.
