What we know:
1) Human raters work as a control group for the Google engineers (confirmed by Matt + leaked manual documents). They use the data to improve the algo. But Google says the raters are not used to directly change the rankings.
2) There is also a confirmed webspam team punishing bad boys and giving whitelistings (on algo level) for specific sites (also confirmed).
Is Google also using human raters to directly change the rankings of specific sites in a positive way or is this done only through the algo?
