Website spamming is a way of life on the Internet. Unscrupulous people can cause serious problems with your website by repeatedly registering, posting useless comment links, and other unsavory things to forms on your website.
For smaller websites, having an active moderator can be very effective. You can set Drupal to only allow users to register or comments to be posted after administrator review.
The following methods can help you to alleviate form spam issues on your website:
Note:
The methods listed on this page aren't meant to be an exhaustive list, and may not meet your website's particular needs.
Method
| Description | |
|---|---|
| User Moderation |
To set registration moderation, visit the account settings page ( |
| Comment moderation | Comments can be turned off on a per-content type basis. You can also limit permissions so that only registered users can comment, and you can also set up comments to turn off after a certain period of time by using the Auto Close Comments module. |
| CAPTCHA | While moderation is good, it's not scalable to have to rely on one or more people for monitoring. This is where up-front deterrence methods come into play. CAPTCHA provides a challenge image and can be used on most user facing Drupal forms. The CAPTCHA module's project page includes links to several modules that enable this functionality for your website, including the reCAPTCHA module. Take care with CAPTCHA modules on Acquia Cloud, because they can bypass the cache and massively increase website load. Other alternatives include hCaptcha and Friendly Captcha which are designed to respect privacy. |
| Registration Validation | Registration Validation allows site administrators to configure custom validation rules for the user registration form. This is helpful when bots and human signups are outsmarting regular CAPTCHA validation. |
There are several other options available for spam control, including the following:
| Module | Description | Drupal 10 | Drupal 11 |
|---|---|---|---|
| Email Validator | Provides integration with a third-party service for email address validation. | | |
| Advanced Email Validation | Uses the open-source stymiee/email-validator library to validate email addresses using advanced, configurable rules. | ||
| Honeypot | The Honeypot project is well supported, and has additional features that some users may find helpful or more secure. It can require some minimal configuration and maintenance to continue performing at optimum levels. Be aware, if you configure time based settings, Honeypot may bypass Varnish and increase server load. | ||
| Antibot | The antibot module requires end users to have Javascript enabled before they can submit the form | |
