Be smart. Never make the same mistake I did. Never add your black hat sites to google webmasters tools. It is not worth it. You gain nothing but loose everything. Why on earth would you add your sites which are black hat to algo which you are fighting against? I guess one has to experience this to learn this valuable, yet stupid lesson. 7 of my sites which were added to webmaster tools all got manual penalty. Two other weren't added - still alive and kicking. Take care, I am off to rebuild everything from scratch.
