pure spam content for google webmaster tool, and all the sites been de-indexed i have to start over but there are still three questions: 1. about doman: i have several clean domains, but they are registered together with the punished domains in the same account of namesilo, can i use them? 2. about hosting: can i keep building my new sites in the old hosting(the old ip)? Should i have to buy a new one? Will google find there are some kind of connections between the new and old sites? 3. about content: i think i can just ues the old content to my new sites because they are not indexed by google now, right?
