WordPress is one of the powerful and famous open source blogging software. Most of blogs are wordpress as it is free and easy. So spammers can easily target the wordpress blogs. I am talking about spam comments. Most of spammers are looking to promote their products or for build backlinks. Here are some tips to prevent them.
How to stop spam comments on WordPress?
1. Akismet WordPress plugin
This should be the first important step. Akismet is an automatic spam killer. You should install and activate Akismet plugin. This WordPress plugin will automatically detect spam comments,trackback and protect your site.
Akismet plugin is installed on your wordpress blog after you install it. You need a Akismet API Key to activate and you can create the API Key at Akismet.com. It is Free.
2. Always moderate comments
It is difficult to moderate each comments. Even you install Akismet Plugin,there is chance for spam, or sometimes it will move non spam comments to spam page. As it is just a plugin not human. Moderation is not essential when you activate Akismet but better is to take a look at comments once a week. Change comments settings from default settings. You can change it in menu -> Settings > Discussion.
Better is to leave the following option:
“Comment author must have a previously approved comment”
Spammers can easily make you fool, they may appreciate your post to approve comments. When you tick this option, spammers comment will automatically approve whether you made any mistake in first time comment moderation.
Make sure that you check the following option:
“Comment author must fill out name and e-mail”
3. Use Comment Blacklist
This is an another great way to stop lots of spam. You can do it in comments settings. In comments blacklist section you can enter the words, IP address, URL or email that you need to block. If any comments detected any of these it will moves to spam folder.
4. Use Captcha

Another way to stop guest commenting spam is to make comment section only for registered users. To use these settings check the following options in comments settings:
