I have a question regarding the use of public blog networks, I this is a newbie kind of question so please bear with me for a moment. Say I was to use the services of a Public Blog Network and that particular network was to be outed and de-indexed what would happen to my own website. Would I just loose the links or worse would i be hit with a manual spam action by google? I was really curious to hear from others on this issue, did anyone face this issue before? I guess ideally building my own private blog network would be the way to go. Even then though if my network were to get hit would this cause some sort of spam penalty or would it just be a loss of backlinks?
