Thanks for the information about removal of a message without a RR.
@Shai - Yes, but work had been done on removing links from sites under their control. Still early days to observe the effects of what they've done, as Google's de-indexing of those links and others is continuing - could be several months or even more depending on how Google handles their penalty refresh timelines.
Also, since Penguin is algorithmic, I don't think removing partial matches need necessarily be a cause of that penalty. It could be indicative, but I don't know.
No disavow file is involved yet, although that may come later for that particular site which is Penguin penalized.
Any serp movement to accompany this occurrence?
