@Inspector: That statement by John Mueller is quite confusing and puts the notion of a penalty (aka manual action) on its head. It implies that the algorithmic rankings have precedence over a manual action (the only way there can be no change after an actual removal of a manual penalty) which simply cannot be true because in that case there would be no reason to have a manual review/penalty process. Google is very skimpy on human resources and they would not waste human labor on a process that was not essential. A manual penalty has to be a huge dampening factor and there should be SOME positive change after it's really removed. So my hunch is that they are not too quick to remove a penalty. Perhaps they don't want to remove it at all (whatever reason might be, technical, punitive, whatever) and send you the notice just to get you off their tail?
BTW, the site in question in that post (from the Google Product forums thread linked there) is also still suffering from the penalty, some 8-9 months after Google sent them a "revoked" notice, judging by their current traffic stats (from third party data sources, should be noted)
