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).

Question:
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?
