Ask anyone with a WordPress website, and they will tell you that they have (at least in the past) fought a losing battle with comment spam and profanity. It matters less whether yours is a small site or a mammoth platform, spammers and profane people will mess it up for you in two major ways:

  • Firstly, profane content will send your prospects away
  • And secondly, spammers will taint your SEO rankings on Google

On profane content, excessive use of, let’s say, adult language and cursives will decrease sales and send away potential partners. Nobody wants to collaborate with profanity. Nobody.

Comment spam on the other hand ruins your rank in Google, sending your site (hence products) to oblivion. Spam scares human visitors as well, which leads to nothing but a very thin bank balance.

In this post, we will talk about ten (10) spam blocking and profanity filter filter plugins. You will be able to improve your SEO rankings, provide a richer user experience, and ultimately reap better rewards for your efforts.


Top 5 WordPress Profanity Filter Plugins

WebPurify Profanity Filter Plugin

This is why:
You needn’t create a blacklist as the plugin comes packed with an extensive multi-lingual blacklist

WP Content Filter Plugin

This profanity filter plugin has grown smarter by the update. For instance, the plugin is intelligent enough not to strikeout “pot” in “potbelly” if/and when you flag “pot”.

Another thing, you can replace all letters in the profane word or retain either the first or last letter. For example, “pot” would appear as **t, P*t or p**.

Additionally, you can choose to filter different areas on your website i.e. comment section, tags and even post titles.

Word Filter Plus Plugin

This plugin goes beyond a profanity filter. I will explain. Instead of just replacing letters with wildcard characters, you can replace the profane word with a word of your own.

Just download and install the plugin. Then access it via Tools -> Word Filter Plus, and set your filters. Once your filters are up, the plugin will go through your entire website removing profanity.

You can also replace certain parts of your content with new content. For example, you can change your telephone number all over your website without editing individual pages separately.

Defensio Anti-spam Plugin

A spam blocker and a profanity filter, Defensio Anti-spam plugin will stop comment spam and rogue users on your website.

The following are some the features the plugin is known for:
Malicious content detection
Script detection
URL categorization
Profanity filtering
Et cetera
Even though Defensio Anti-spam “…learns and adapts to your behavior and that of your users over time…”, it doesn’t play well with other spam-blocking plugins such as Akismet. This means you will need to deactivate Akismet and similar plugins to try Defensio Anti-spam.

Word Replacer Plugin

Just like the Word Filter Plus plugin, the Word Replacers profane word with your words.
The only demerit is the fact that the plugin does not come with a blacklist, so you have to spend a lot of time setting up word replacements. But once the replacements are in place, the plugin works automatically.

You can filter certain areas of your website while completely ignoring others with the plugin.

Now that we have profanity well taken care of, how about we stop spammers dead in their tracks.

This plugin lives up to its title by using CAPTCHA technology to validate and capture comment spam. If it detects spam, it stops it immediately because, well, it’s SPAM stopper.
The plugin is easy to configure and use, and it stops spambots (automated spam) that assault blogs.

Growmap Anti Spambot Plugin (G.A.S.P.)

If only this plugin had as many downloads as Akismet, it would oust the latter as the leading anti-spam plugin out there.

With an impressive rating of 4.9/5.00, Growmap is an effective tool against spambots.

It is a great anti-spam plugin to fight against spambots, but its severely disadvantaged as far as combating pingbacks and human spammers goes. But that’s probably because Growmap do not concern themselves with human spammers but spambots.

Growmap uses a checkbox where users tick to verify they aren’t spambots. This does not stop human spammers though.
