Congratulations, this means that your KS Blog has found its way into the blogosphere. Once a blog gains “visibility” in search engines it will become the target of comment spam ( http://codex.wordpress.org/Comment_Spam).
The good news is by default, comments are moderated, so they never make it to the blog’s public view (please do not change this setting). The blog admin simply has to delete the offending comments. We are currently using several anti-spam technologies which catch most of the comment spam, but some will still make it through. This is a normal part of blogging.
