This could have been a paid review through ReviewMe, it was ordered a few days ago and I just haven't had time to write something that warrants being paid for it, but I decided to write something for free.
If any of the Google Spam Team are reading this article, it was not paid for in any way and your bots can't tell the difference because keyword analysis would pick up the specific words suggesting that there is some kind of disclosure for paid links.
My paid reviews are not cheap, but they are often worth it – people are paying me
Wide Circles = Blog Comment Spam
Maybe I am a little sensitive to blog comment spam issues, but I like genuine members of my community gaining a little link juice for their comments. Many comments you find on my blog are better than full blog posts elsewhere (sometimes the comments are better than what I write)
The best way to guest post on my blog is just to write a great comment.
