I did a few site wide 301 redirects and they punished the old trusted and the new domains with a -50. They moved 14 domains in the penalty box.
This was definitely done manual, they only missed one domain.
What a bunch of ....
They even punished domains where there was no 301 redirect in place. It seems the 301 redirects raised a flag and the manual demotion catched almost all domains. This was a damn lazy reviewer.
