This is actual high pr 1 - 6 pages from over 700 EDU domains (PR up to 8) where you can drop your comment and if it is good enough and meaningful more likely you get approved. Just imagine 5000 plus totally white hat backlinks pointing to your site! I recheck and scrape additional entries weekly, latest check was made 22/02/2013. Note this is not auto approve list or blast! You must comment by using Your favorite software or by hand. For better success rate I suggest drop meaningful on topic replays, avoiding overused "great site" or "great post" . Some posts take a while to approve, depending how lazy is site admin, but good news is that in this case they appear natural and whitehat to SE robots. Remember - do not share this list, it dramatically decrease Your own success rate in future, even small payment is good barrier to Your competition....
thank you...
