Well, I just had to turn on the comment moderation. I don't like to do that because I like the comments to show up right away. Especially if I am not going to be by a computer for awhile.
But yesterday I had several spam comments. Those are comments from people who really have no interest in your blog, but want to put up a link to their website so that they can get more publicity. So, when someone says "Hey love your blog." and then adds a link to Jordan Shoes... Yeah.
So I am now going to start moderating the comments.
