Google does not officially deny the existence of negative SEO anymore:
A new market is born:
Lot's of SEO's are reporting requests to spam competitors - Google's spam team have lost touch on reality.
And it works:
I blasted it for 3 months straight and it went from position #1 to the top of page 4.
So, did you make a mistake and you got punished by Allmighty G? No problem: if you now rank #40, just blast #1-39 and you're back on top!
