All that taken together makes me pretty sure it's not a penalty, it's a whole new scoring metric.
You can call it whatever you want, filter, negative algo points or whatever, but am using the term "spam penalty" because that is the term Googleguy used in a post about the 302 problem from years ago causing a decrease in Pagerank -
"In many of the cases that I've examined, a spam penalty comes first. That spam penalty causes the PageRank of a site to decrease."
