Google uses trust metrics so while a site is brand new and has no jealous competitors they are determining whether or not that new site is of any value.
Tomorrow someone could register a brand new site, add the most viral piece of content there has ever been and Google?s machine learning algorithms will know which signals to look for and which signals look manipulative. A brand new site can still rank high naturally with a huge burst of backlinks but if that burst comes from manipulative methods be sure Google will know.
Now if someone does some kind of xrumer blast or whatever people are using now, Google knows what?s going on, that blast MAY help temporarily but it may have negative effects on newer sites as they have not earned the trust yet. Blast an established authoritative site that is ranking competitively and the worse that can happen is those backlinks become devalued.
As your site ages Google knows what kind of backlinking patterns to expect.
You can?t just say ohh i?m going to blast all my competition so I become number 1, it does not work like that. Google have some of the smartest engineers in the business, they spend billions of dollars perfecting their algorithms and have in excess of 20,000 employees.
I highly recommend that you read the book ?In The Plex? which can be found
