Blog comment spam is insidious and annoying. These are comments left on your blog that are only designed to lead your readers to an outside website. Usually these websites are commercial in nature, but sometimes they are dangerous, leading your readers to download viruses that could destroy a computer. Not only are these a problem for your readers, but they make you look unprofessional. And while something they are easy to spot, some of these comments will be more difficult to ferret out.
The first thing you should do to keep your blog free of spam is to enable comment moderation. Most blogging platforms allow you to keep comments from posting until you have had a chance to review and approve of them. This is definitely a feature you should be using. In addition, if your blogging platform has an automatic filter to help identify spam, you should use this as well.
It is sometimes tempting to turn off comment moderation if there’s a conversation going on between your readers and you have to leave the computer for an extended period of time. Don’t do it. Disabling comment moderation only allows spam to fill up your comment boxes. If you do have to go away and cannot moderate your comments at all, turn all comments off until you return. It will save you a great deal of hassle in the long run.
Some blog platforms offer a ‘blacklist’ option. You can ban certain words without ever having to moderate those comments. While this is a great option for some words, there are other words that you might want to add but shouldn’t. For example, adding the word ‘financial’ to your blacklist will mean that any comment, even a legitimate comment, will be completely removed. Instead, choose comment verification, which forces users to prove that they are a real person, not some robot posting automatic comments.
Now that you’ve started moderating the comments your blog receives, you’ll have to decide if the comments you are getting are legitimate. As a general rule, legitimate comments will be relevant to your original post. Spam comments are often unrelated and include a link to an external, usually unrelated, website. These should be deleted immediately. Legitimate comments can sometimes have a link embedded, but this link will always be relevant.
Check the handles of readers posting comments. The handle might have a link embedded, but a legitimate link will always lead to either the commenter’s blog or a home page. They will not lead to commercial websites or anything selling Viagra or offering to check your computer for viruses. These are spam. You should also be wary of allowing anonymous comment. Most spam will be posted by the dreaded anonymous user.
Some spam comments are more difficult to recognize. However, if you see a comment with horribly bad grammar or a post that is so generic that it could apply to almost any blog post on the Internet, then the comment is probably spam. For example, “Great post … visit my blog” doesn’t usually lend anything to your blog at all.
If it looks like spam, it’s probably spam, and it’s always better to be safe than sorry. If you think it’s spam, delete it anyway. At worst, the commenter will have to repost it later, and then you’ll be closer to knowing for certain that it isn’t spam. Err on the side of caution and your blog will have a clean look that is free of spam.
