Even though WordPress may be the most popular blogging platform out there, there is no doubt that users of the software can be faced with hoards of spam problems. Spammers seem to target the blogging platform as a way of obtaining free advertising and backlinks for their own websites and this creates a massive problem for blog owners. Fortunately, there are solutions available, with users at least able to employ various plugins that are designed to beat such spam. Here are some Anti spam Plugins for wordpress.
Comment Spam Wiper
Comment Spam Wiper is regarded as a very popular spam detection plugin and the fact that it has been downloaded almost 5,000 times and possesses such a high rating within the WordPress community speaks volumes about its success. The plugin is based on a database system and whenever someone posts a comment on your blog, it is automatically checked with the Comment Spam Wiper spam database. If there are no matches, the comment will be allowed to stay, while the opposite will occur if there is a suspicion of spam. One of the impressive features of this plugin is that users can manually mark spam comments, which will then be added to the system’s database for future detection purposes.
This plugin takes a slightly different approach to spam detection. No SpamNX utilises the method of adding invisible form fields to the comment form and this tends to impact the spambots significantly. Most of these bots are designed to complete every field in a form and as these additional fields are invisible to the human eye, it’s easy to see when a bot is accessing your form and attempting to spam your blog. No SpamNX also gives users the opportunity to develop a blacklist containing common spam words or phrases. This means that a comment is automatically blocked from being published as soon as a human spammer attempts to make a post with such a phrase.
Spam Free WordPress
Boasting almost 250,000 downloads, Spam Free WordPress is certainly one of the most popular plugins in this field. The plugin makes plenty of guarantees about its effectiveness as well, claiming to block 100% of automated spam with a zero false positive ratio. The author claims to use a range of methods to block spam and the feedback from the WordPress community is incredible. Users are also provided various options with this plugin; for example, they can add a local IP blacklist to deter renowned spammers, strip HTML tags from comments or even immediately throw any detected spam into the trash bin.
As the name of this plugin may suggest, WP-reCAPTCHA uses CAPTCHA technology to implement its anti-spam methods. In simple terms, reCAPTCHA forms will provide the end user with a distorted phrase that has to be repeated for the comment to be published. This method is one that has been used for a long time and while spammers did at one point find out how to use software to bypass such obstacles, this is no longer the case. The fact that most industry level scanners cannot read these phrases suggests that spammers won’t have a chance and this is probably the reason why over 360,000 users have already downloaded and experienced success through this plugin.
However, if you thought the previous couple of solutions were successful, Akismet takes spam detection to the next level. It is by far the most downloaded anti-spam plugin for WordPress and the fact it has almost 12m users speaks volumes. The way it functions is very similar to Comment Spam Wiper, with Akismet checking each posted comment against a huge spam database. Personal blogs are allowed to use Akismet with a free API key, although commercial sites must pay for the privilege.
