I have a list Ive gathered for scrapebox and Ive used that list to blast my site already. I also have 30 backlinks from article directories like ezine, goarticles, etc. Can I use that same list ive already used on my site to blast backlinks to the article directory sites? Ive been reading about those pyramid linking systems and want to give it a try. So basically will google notice this and penalize me, or should I just harvest a whole new list for my web2.0 links?
