Got some spare time so I'm just sharing one more SB method. Hope you like it. I highly recommend Drupal for blog commenting as they are do-follow by default and generally the comments are auto-approved. I always come across high PR pages in Drupal blogs! The only problem is you need to register for an account to post comments. It's a big head ache when you do the manual blog commenting in a large scale. Actually there is a way to harvest auto-approved Drupal blogs which doesn't require registration. I'm gonna show you how I do it with Scrapebox. I used the same technique for harvesting the list which I shared last time. If you don't have SB, you can harvest the same manually from G0ogle by using SEO Quake FF plugin. The above give is the phrase which appears in the comment section when you submit your comment to Drupal blogs which doesn't ask for registration....We need to tweak the footprint little bit to find the Auto-approved blogs. That is where comment submission date comes in to picture. So this footprint shows that this comment was posted on June 25th 2011 by an unregister user. Now we are gonna utilize the Time Span option in SB to harvest recently indexed pages with the comments posted recently (within a week) Hope you get my point. Basically we are trying to find recent posts which has comments approved the same day or within a week. I noticed that not all Drupal blogs use the same date format so we need to compile a list of footprint with variations in the date format. Like this... Put the above in Keywords field select ONLY G0ogle for harvesting Set the time span to past week start harvesting Manually post a comment to test the comment moderation. Most of the harvested blogs won't ask for registration and approve your comments instantly! You can even harvest EDU/GOV Drupal blogs in the same way. Just add site:.edu(for EDU sites) and site:.gov(for GOV sites) in the Harvested field along with footprints in keyword field. Once you find those blogs, harvest all the pages from the blog and use it for blog commenting. If you don't have SB, use the timeline option in the search tools to see the past one week results. You can install SEO Quake to sort and save the listby Page Rank.
