The plugin protects Joomla! core forms that support the plugin group Captcha like the user or contact component from the core or any third-party extension supporting the Captcha implementation provided by the application. It is a simplified version of the plugin EasyCalcCheck Plus Pro with five internal anti-spam check mechanisms: an arithmetical problem, a time lock, a hidden field, a JavaScript field and a self-defined question.

Features

• Arithmetical Problem
  • Involves simple calculations that humans can solve easily.
  • Limits automated entries as bots typically can't solve these problems.
  • Easy to implement, requiring minimal system resources.
  • Offers adjustable complexity.
• Time Lock
  • Measures the time taken to fill a form; bots usually fill out forms instantly, whereas humans take longer.
  • Provides an effective barrier against automated spam attacks.
  • Automatic function that requires no input from the user.
• Hidden Field
  • Invisible to human users but detectable by bots.
  • Bots usually fill out all fields, hence, filling out a hidden field indicates spam.
  • Simple to implement in any form.
• JavaScript Field
  • Requires the user to have JavaScript enabled, which many bots do not.
  • Helps detect and block bots since they can't execute or interpret JavaScript like a web browser.
• Self-Defined Question
  • Customisable and flexible; can be as unique and creative as you want.
  • Effective against bots since they usually can't understand the context or unusual questions.
  • Allows for a site-specific or target audience-specific approach to anti-spam.
  • Requires some thought to create a question that is easy for your target audience to answer but hard for a bot
