When it comes to content management systems, WordPress is amongst the favorites for the majority of bloggers, webmasters, and business owners. It’s easy to install, it’s super flexible, and with the large number of professional WordPress themes and plugins available, you quickly get the feeling that you’re in charge of everything that happens on your WordPress website. However, the popularity of WordPress makes it also an attractive target for spammers.

Luckily, WordPress is an open source project and therefore often eliminates the need to hire an expensive developer/designer who could code the perfect site for you. Instead, you can rely on the vast amount of information and free tutorials that are available on countless WordPress resources. This is ideal to educate yourself and create a modern, professional and unique website at very low cost.

WordPress by itself is a fairly safe and secure piece of software. Potential WordPress security problems are usually addressed instantly and there haven’t been that many major security breaches throughout the years. However, there is one annoying thing in particular that WordPress users will most definitely have to deal with: Spam.

WordPress comment spam and other spam attacks

WordPress attracts hundreds of thousands of spammers who try to squeeze out an accepted comment out of every page they can get their hands on. Spammers try to use WordPress sites to place shady links, inappropriate advertisements or other malicious content. However, WordPress spam doesn’t only occur in the form of spam comments. WordPress contact form spam is another common issue, as well as user registration spam.

Akismet Blocked Spam Comments

As just one example, the above screenshot shows what spammers can achieve in just over a years time. More than 200,000 spam comments have been filtered. Who knows how many more are attempting to spam every single day. Spammers will spam comment boxes, user registration forms, contact forms, and any other form that allows an input; which is why it makes sense to look out for a spam protection plugin, the only way to keep spammers at bay for good.
