As You can see I dont peak here a lot, just few times a month. So please imagine how many spam comments I’m finding when logging here… But I got to say I like to read those spam coments - You can watch how blog spammers evalueting…
Even with the NOFOLLOW - as always - every link has an importance of gold 
Of course I know nothing about black hat seo techniques ;)) Anyway I’m finding 2 different kinds of wordpress spammers - Those who “combine” a little and those who dont.
The first kind comments I like to read the most and this post is about them. These ale comment like:
“I like Your blog”, “Usefull info, thx” or “I like the way You write” (plus one link to some website.. to look natural) Yeah I like it too ;D Althought sometimes it happen to see coments with a lot of really good content - for example few weeks ago I have find a comment with one link in Sex toys article, which had a weight of 8kB of text and I was few times longer that my post ;D - but this I can appreciate! Good Idea - link with proper content and keywords density!
I have one more digression about the “Like Your blog” comments though, it remindes me very specyfic Friend TV Show scene. Its Monica, Chandler and Pheebe talking, Pheebs is writing her “book”.
Chandlar: Pheebe stop typing about me and Monica, using ours exact words!
Pheebe: It’s not about You and Monica, Its about.. (some names), and how much in love are they..
Monica to Chandler, smiling to each others: Ohhh, how nice..
Pheebe: And about how people believe in everything You say as long as it’s a complement…
And to be honest it works the same way with the spam comments - sometimes it happen to me to accept those comments It’s always nice to be nice
