Negative spam comments – why?

I get a lot of spam comments coming into this blog – I take it as a compliment that they see my blog as worthy of their effort to get included in it. Generally, the spam gets filtered and deleted automatically, but occasionally I look through the comments.

Most of the spam is along the lines of “Thanks for great information” – presumably on the assumption that I will be flattered and approve it 🙂 Sometimes, it is a question like “who made your blog look so good?” Either way, the links and names not matching emails help give away the true nature of such comments.

Tonight, however, I just read a spam comment that was highly critical of my blog*. I just don’t understand their thought processes – who is going to be sucked in to approving spam that attacks them? Obviously someone who has a lot of spare time if they can send out comments with no chance of being approved to earn them links!

Am I missing something? Have you come across similar pointless comments in your blog?

At least the next comment I read was honest “I am desperate for back links so am putting comments in your blog.” I didn’t approve it either, but they had more chance of success!

*Apart from the obvious link and name clues, I know it was spam rather than a genuine complaint because it accused me of whining in that post, yet the post was a pair of definitions in my Monday Meanings section!
