Now I can use scrapebox to find auto-approve blogs and post on them - easy enough. My question is, are backlinks from these spam-able blogs worth any? (most of them have no PR anyway) My impression is that, google should somehow know that, these blogs are spam-able and links from those are worthless/or even bad to the site linked to it? I do ~200 backlinks per day per site for a week now, and didn't see a site ranked better due to these backlinks, and some of the new domains(less than 1 month old) are not even getting indexed. So I wondered whether this can be caused by all those spammy backlinks, or I have to wait more than a week to see results? Am I just too paranoid about those backlinks? Any opinions on this?
