Prevent Comment Spam
Recently, our blog is flooding with many comment spams from sites selling drugs and adults things. Luckily, we do not automatically publish comments. Indeed, we will review all comments.
In addition, we use a special feature from WordPress: Add ref=nofollow to all links in the comment areas. So, no people can manipulate their search engine rankings through comment spam.
Also, we’ve already ban those IP address.
If you have a blog, you can take the above steps. It can reduce lots of headache.
