Google made negative SEO possible - you know, that dirty little secret that no one talks about and that is frequently the explanation for why a site just won't rank no matter what - and now it seems easier than ever. Not only could you neg-SEO a site by spamming it with junk links, now it appears you can spam their Tier 1 links with thousands of garbage links per day and use that to take them down, confident that Web 2.0 platforms will make neg-SEO even harder, if not impossible, to track down the culprit.
On top of that it's now known that you can take down a site by 301'ing a penalized site to it. And as of today there are more penalized sites than ever!
Thoughts on this - is negative SEO going to become an even bigger problem than ever now?
