I'm late in here, but a sub domain strategy sounds as though it's not for everyone. It could give temporary relief but badly backfire for a large number of reasons.
Again, repeating what's already been said, nothing new here about why the HubPage content is visible and ranking.
noone has recovered simply from removing "bad" content.
Some claim to. But effectively it's a complete and costly site rebuild for some. Some won't make it. The alternative is to choose to do nothing and move on to other things.
Sites that fix , will be back - when, who knows. This is a penalty with a manual on/off switch like PR in a sense. for those effected, let's hope it's not years.
