If you have a blog you already know that comment spam is a fact of life. We will discuss here how to prevent spam on your blog. If you are using WordPress as a platform for your blog you have solid built-in tools to prevent comment spam as well as a wide range of comment spam defense and protection plugins to choose from if you need additional coverage.
Akismet Comment Spam Fighter
All current versions of WordPress features the Akismet plug-in installed by default. Akismet combines a community created database with common comment spam with a unique algorithm. In order to enable Akismet on your blog, you need to activate the plugin from the Plugins panel. After you activate the Akismet plugin you’ll have access to a menu added to the Comments Panel. You can mark any comment spam that gets through Askimet’s net in your Comments Panel.
Nofollow Comment Links
New bloggers sometimes add plugins in order to change in comment author links the nofollow attribute. The reason is that they try to have more users leaving comments on their blog when the links are marked dofollow. However, this is not recommended because it might lead to an increase in the frequency of spam comments. Most of the comments on the blog, even if they are non-spam comments, are coming usually from users who are interested more in the link back than in in the discussion. It is more important to have quality blog comments than a high number of comments. For this reason it is not recommended to mark your links dofollow and use plugins that links via comments.
Reduce Comment Spam Using Cookies
You may also install the WordPress plugin Cookies for Comments. Spam bots use automated scripts and for this reason they don’t download stylesheets or images. When a spam boot accesses a page with comment form, the Cookies for Cooments plugin sends users an image file or a stylesheet and sets an identifying cookie.
Use Honeypot to Block Spam Bots
Honeypot plugin is based on technology that effectively cheats spam bots to identify themselves. Install the WP Spam Fighter, then go to Settings in order to enable protection using honeypot.
Use WP-reCAPTCHA plugin that require users to type the characters shown in an image in order to filter out spam boots and accept only manual comments. Recaptcha works effectively in blocking spam bots, however it cannot protect your blog from human submitted spam comments.
Remove the Website URL Field
If you leave in the comment form the URL field you may attract both human and automated spammers, as well as people who are not really interested in discussion. For this reason it is recommended to remove from comment form the URL field, in order discourage spamming behavior on your blog or website.
Other methods to discourage spam on your blog are:
· Turn off Comments on Media Attachments· Disable Comments HTML · Disable Trackbacks· Disable Comments on Old Posts· Switch Off Comments
- Reducing the Number of Links in Posts
- Using Comment Blacklist

- Pre-approve Comments from Old Commenters
