Customer Referral Spam Blocker

Not only does referral spam mess up your Google Analytics statistics, it also serves to help spam websites build up their search engine rankings. This makes these spam sites appear to be legitimate. Essentially, the referrer makes multiple requests to your site using a bogus referrer URL. This adds the spammer’s URL to your statistics, and also causes search engine spiders to index the spam site. This plugin blocks these and keeps them out of your analytics stats.


There is no doubt that spambots are a problem for WordPress websites. Unfortunately, forcing users to enter in confusing and hard to read characters from captcha images is also problematic. This is why WPBruiser exists. It catches and blocks spambots from regisitering on your website or leaving comments, without forcing people to use captcha. Many other plugins only catch spammers after they’ve already registered. This means you have to do the real cleanup. WPBruiser gets them before they even get in the door. Another feature that many webmasters find attractive is that this solution doesn’t access any external databases. It is entirely self-contained.

CM E-Mail Registration Blacklist

This plugin prevents your WordPress site from spammers who are trying to register on your website. It checks users against databases of known spammers, and lists of blacklisted domains. If the user shows up on any of those lists, their attempt at registration fails.

SiteWide Comment Control

In most instances, when a spammer or troll decides to target the comments section, they tend to stick to a single website on your network. Handling this is easy. You simply lock the spammer out of the site. However, every so often, a spammer decides to make a special project out of an entire network, and they begin spamming all of your websites.

SiteWide Comment Control allowsw you to manage spammers over your entire network by blackholing their comments, sending them to a spam queue, or putting them on moderation. The last option is great for users who are new to your network and not yet vetted out.

For example, someone posting a list of best apps as their first post might be suspected as someone doing affiliate marketing for the makers of one of those apps, so you would keep them on moderation until you were sure they were a legitimate follower.
