No. Blog spamming is if you went to other people’s blogs and made an entry saying: “I agree with everything said here” and left your site as signature.
You do this to 100 blogs and all the signatures you left are counted as links from the blogs to your site and increase your PR.
You have absolutely nothing to worry about except having to clean up after a bunch of people who will be spamming your blogs.
Well, maybe you have to worry about me complaining about your not linking to me with your topic related blog……
