Integrating Learning Into Spam Prevention Measures
Resisty is a CAPCHA plugin that adds a new twist to spam-comment prevention measures.
Resisty is a CAPCHA plugin currently available for WordPress that adds a new element to spam-comment prevention measures. The system verifies a user as a human by asking them to perform a small task.
The developers explain below:
This plugin will draw a random 5% or 10% resistor and four color band sliders beneath it. The commenter needs to match the colors on the sliders to the colors on the resistor. Commenters don’t actually need to know how to read resistors, but this will help them as they post comments on site that use this plugin.
