Quintura Search & Blog Comment Marketing - Spam?: "What Quintura Has Done Wrong - The thing that really bothers me about Quintura’s blog commenting campaign is that it looks like the people behind it, unlike most blog spammers, actually took the time to read the blog post and offer some attempt of relevancy in their comments.
