Not sure what's going on here but here's one such example from the last couple of days where the seller was busted: http://www.blackhatworld.com/blackh...in-names-great-pa-da-create-your-own-pbn.html Now this guy sarkar selling CAPTAIN JACK SPARROW, SHERLOCK something & GALAXY BLOG POSTS, notice all of the extremely postivie reviews are from noob accounts that have 10 - 20 posts 40 at the most. On a closer inspection of only 2 - 3 pages I was able to pick out all noob usernames that I am 90% sure duplicates created by the seller himself as they MOSTLY only comment on his various threads all over the marketplace. Check these out, I picked them out only from 2 - 3 pages. http://www.blackhatworld.com/blackhat-seo/members/763488-backlinking4u.html http://www.blackhatworld.com/blackhat-seo/search.php?searchid=9462029 http://www.blackhatworld.com/blackhat-seo/members/789496-intervinemanagement.html http://www.blackhatworld.com/blackhat-seo/members/78195-kaminas.html http://www.blackhatworld.com/blackhat-seo/search.php?searchid=9461968 http://www.blackhatworld.com/blackhat-seo/search.php?searchid=9462131 There are many more, if you want go and look for yourself. Again, I might be wrong but this looks awfully fishy but I will let you be the judge of that! Be safe and only buy from trusted sellers!
