What I have been thinking about also is the sandbox effect. What if Google got the sandbox out of the filtering... that would absolutely makes sense in some way.
For example: we launched a website in spanish and put it on an .es domain. That site is indexed normally with a top10 rankings. This site has almost no links other then from the main domains which have been there for years.
Strange innit? No authority yet but increasing in traffic. Other sites WITH authority keeps decreasing in pages and visitors.
