I have more than 300 web properties which I used as tier 1 for some website that has received a manual penalty for unnatural links. How can I tell if these/which have been penalized as well? All have unique content, PA +30/40. I would like to use those for another website but I'm not sure if that would be a stupid move. If I search for sentences used in articles, they do come as the top result. Any ideas are greatly appreciated!
