Spammers

I am having a problem with spammers on my blog. They are annoying, obnoxious, and some are even perverted. So I am politely asking that whoever you are, to GET OFF THE BLOG!!! This is a family style blog, and although the readers do not have to read the comments (since they are being moderated) I do, and I am done. I do not want to go private, but the perverted comments NEED TO GO!!!! Whomever you are, read the comment at the top of the comment box " if you not have anything nice to say, don't say anything at all!!!" If anyone has any tips about how to go about getting rid of certain readers, without going private. I love to read comments normally. But now, I take a deep breathe in before I look at the comments. I will keep on posting, but I really need this to change. So look forward to more posts, and I hopefully will look forward to reading some kind and wholesome comments. Thanks.
