I have a question concerning using Scrapebox to fast comment to a list of pr-approved comment blogs. I'm about to run a blast using money sites as my links. The sites are all fairly aged and have some other backlinks already. Is there any downside to using my money sites since these are pr-approved comment blogs? Should I create some 2nd tier sites to link to my money site and blast those links? If anyone can offer some insight I would be very appreciative.
