---- It is easy for competitors to hurt established sites (negative SEO)

Negative SEO does exist. It's not conjecture.
If people are still debating whether it exists or not, they need to look at the facts. Penguin goes after bad links and as long as links do not leave behind a social security number or DNA, then Google will have a really hard time determining who created the links. Even with Adsense code on the website and a person being logged into Google, the amount of computing power needed to determine who created a link would be extraordinary. I don't think Google has evolved to this level yet. No matter, bad links are dealt with by Google with their algorithm and manually. Nothing positive comes from having bad links pointing to a site, which is why people who say negative seo does not work are uninformed. Obviously negative seo won't work on big or Google protected sites, but many seo blogs cite cases of effective negative seo attacks on smaller websites. Anyone ranking good in Google is a potential future victim.
