let me tell you bluntly what has happened.
Your business model is no longer viable. You had a nice little earning system, but it relied on tricking Google into thinking your sites were more valuable and more interesting than they were. It was nice while it lasted, but your time's up!
Those sites will never get reincluded because your sites are not what Google wants in the natural search. Your sites are not being penalised, they're being accurately assessed. After all, they have no original content and offer no added value to other people's content, so there's no reason to put them in the search results.
It's time to find a new way to make money.
I'm not saying this to come down on you or anything, I'm just giving an objective opinion.
