I've been reading a lot lately that Scrapebox is more useful in getting high quality backlinks from high PR blogs by manually commenting to them. But I just want to know if there is anyone still using its automated blog commenting to blast their money sites? And if they do, how are you blasting your money sites? Like 10k a day? And what are the results? etc. I just want to confirm if auto-posting is really only useful for tier 1 and 2 backlinks.
