Risk of spam from contact forms: How to avoid it

With each contact form, the risk of spam increases. All these unwanted messages are not only annoying but also increase insecurity. In this article, we’ll show you the dangers of contact form spam and how to best protect yourself against it.

How does a contact form pose a spam risk?

Spam messages are bulk messages sent via e-mail or other electronic messaging systems such as
contact forms are sent. They very often include phishing or malware that can cause serious damage to the site. However, these are usually not manually sent messages.

Fraudsters often develop programs that scan many websites for insecure contact forms. Once enough contact forms are found, they are filled with scripts, i.e. a list of computer commands. With incorrect or invalid contact information, mail is sent and recipients receive spam.

Which forms are endangered?

Basically, any form you use on your website is at risk. In addition to contact forms, this also applies to order forms or forms for entries in the guest book. The key point is: There is a risk of spam if forms are insecure.

The more forms the scripts can fill out, the higher the chance that the submission will be successful. Automation gives scammers the opportunity to submit thousands of contact forms in one go.

What protects against spam messages?

An easy way is to put a barrier before submitting using captchas. An example is Google’s reCaptcha. Here, senders have to enter or check various things, such as a sequence of letters and numbers or ticking a box. In this way, the user confirms that he is not a robot.

These captchas are a hindrance, but more and more fraudsters are looking for ways and solutions to bypass the most common captchas. Website operators can thus distribute the content of the form to multiple pages. This makes it difficult for automated scripts to finally send spam messages.
