Joomla! Development This plugin stops spam at the very source. It leverages major DNS and e-mail black list providers to prevent spam sources from registration and login into your site.

SpambotCheck delivers you real-time spam protection which is constantly and diligently being worked on by various international nonprofit organizations.

SpambotCheck offers simple opt-in configuration for:

  • Black list providers to use
  • Points of impact to survey (registration, registration and login)
  • Spam ID information to use (IP, e-mail address and/or username)

SpambotCheck allows you to maintain your own personalized local listings:

  • whitelist (e-mail and/or IP)
  • blacklist (e-mail)

Get an instant overview of spam attacks targeting your site:

  • Log, view and edit spam attack information
  • Receive incident notification via e-mail
  • Registered users who show suspicious behavior are labeled accordingly

Currently supported black list providers:



  • German
  • English
  • Spanish
  • French
  • Italian
  • Estnian (translation available by
  • Portuguese

SpambotCheck is a small, concise and most importantly a non-invasive plugin, that already offers you about 99.5% efficiency in spam attack protection. The plugin does not need to inspect any contents and therefore is suitable in all situations where there is not any mail text or submission text available.

And even if you are dealing with text submission in forums and blogs, as long as registration and/or login is required, you might consider to use SpambotCheck in combination with additional content analyzing tools that run afterwards. SpambotCheck would then be acting as the outer most tier of any composed spam protection stack that provides you with the highest site protection level possible.

A special version of SpambotCheck is already bundled with our free custom form creator Visforms to protect all your exposed custom made forms right from the start.

Support issues or feature requests are very welcomed at our SpambotCheck user forum.
