- Protect Joomla core forms with our simplified Captcha plugin, featuring five anti-spam mechanisms including arithmetical problems, time locks, hidden fields, JavaScript checks, and self-defined questions. Easy implementation and adjustable complexity ensures robust security without additional system resources.
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.
