Automated spam is nothing new and since most WordPress sites allow commenting on at least blog posts, they become a target. Fortunately, there are simple measures that can be taken to keep this from becoming a massive problem. What follows is a two-fold approach that myself and others use to cut out nearly all spam with relatively little effort.What can I do about all this comment spam?
Require Moderation
Go to Settings > Discussion and you’ll see all kinds of options WordPress has for cutting down on comment spam. What you see below are some default options that are very helpful, so I recommend sticking with them.
When Johnny post’s a comment, you get an e-mail then decide to approve the comment for display on your post. When Johnny comments again, his comment will show immediately, because you already trust him. If you want something more strict, check the box always requiring approval. I have never known this to be necessary, however.
