Better protected against spam with a honeypot

What is a honeypot?

A honeypot is a security measure designed specifically to fool spammers and bots.

This concept actually comes from the world of cybersecurity, where honeypots are used to lure hackers to an apparently vulnerable system so that they can be identified and blocked. In the case of websites and spam, however, the honeypot is a simpler version of this principle, aimed at the protecting your forms and comment sections against unwanted influences.

How does a honeypot help against spam?

A honeypot works based on a simple but clever idea: automated bots fill in every form they come across, without understanding what the fields actually mean. By adding an extra field that remains hidden from the real user (e.g. by CSS) you trap the bot. A human visitor will never see the field and will therefore never fill it in, whereas a bot automatically fills in all fields, including the honeypot.

As soon as the system notices that the honeypot field has been filled in, it knows it is a spammer. You can choose to block the request immediately, give the user an error message or simply ignore the data. By doing so, you keep the user experience for real visitors smoothly, while keeping out spam.

One of the major advantages of a honeypot is that it no captcha required. Captchas can disrupt the user experience by requiring your visitors to take extra steps, such as solving puzzles or entering numbers and letters from an image. This can lead to frustration and even loss of potential customers. A honeypot, on the other hand, is completely invisible and has no impact on the user experience.

Implementing a honeypot on your website

Implementing a honeypot is easier than you might think. Here is a basic example of how to do this:

1. Create an extra field in your form
   This field could be called "phone number" or "address", for example, but make sure it is not meant to be filled in by real visitors.
2. Make the field invisible to real users
   Using CSS, you can hide this field. For example, use the following code to hide the field:
   .honeypot { display: none; }
   As a result, the field will not be visible to human users, but bots scanning your website's source code will still notice and fill it in.
3. Validate the form on the server side
   When the form is submitted, check on the server if the honeypot field is filled in. If the field is not empty, you can assume it is a bot and block the request. You can do this with a simple line of code in PHP, for example:
   if (!empty($_POST['honeypot'])) {
      // This is spam, stop the request
   }
4. Test your honeypot
   Make sure you test your honeypot properly. Fill in your form as a normal user and see if it works without any problems. Also check whether the honeypot effectively stops bots by having a test bot try to fill in the form.

Why use a honeypot?

The simplicity and effectiveness of a honeypot make it an attractive option for any website administrator dealing with spam. It is especially useful if you don't want to integrate complicated anti-spam systems, such as captchas or third-party tools. Here are some reasons why a honeypot is a good choice:

• User-friendly: Because it is completely invisible to the real user, a honeypot has no negative impact on your visitors' experience.
• Easy to implement: With a few lines of CSS and server-side validation, you can quickly set up a working honeypot.
• Cost-effective: A honeypot does not require expensive software or subscriptions. All you need is some modifications to your website's code.
• Invisible to spammers: Unlike captchas, which are recognisable and can sometimes be bypassed by sophisticated bots, a honeypot is more difficult to detect and bypass by spam software.

Spam is a challenge that every website has to tackle sooner or later. While there are many solutions available, a honeypot is a smart and efficient way to prevent spam without disrupting the user experience.
