It' been a long time since almost all pages of SOME of these domains have disappeared from SERP. This happened in April or May 2012 when Penguin was first launched. We've been written reconsideration letters, put off some links, much improved content but nothing helped. We really need some of those versions back. We understand that this is a serious filter and wonder if we could find someone on this forum who could help us. We would hire a person to study our case and suggest (make) filter recovery actions.
I hope there is a magic specialist on this forum who will see this message and get interested
