Anti-Spam Form for Yii2 Framework
=================================

[](#anti-spam-form-for-yii2-framework)

**Anti-Spam Form** is a form replacement component for the [Yii2 Framework](https://www.yiiframework.com) for creating anti-spam forms that are invisible in HTML code to spam bots & harvesting tools.

What's the idea behind anti-spam forms?
---------------------------------------

[](#whats-the-idea-behind-anti-spam-forms)

The concept is simple. Spam bots in most cases are simple tools. They will read your website, look for `` HTML tags and artificially fill up the form fields and post it.

The usual spam bot is a web scraper written in Python retrieving raw HTML webpage content **without** evaluating JS code.

But one thing **missed** in anti-spam detection methods is that spam bots usually cannot process JavaScript code. For a good reason. It's time-consuming and requires JS interpreter to evaluate the JS code within the web page. And it's not that easy to incorporate JS evaluation without using complex & slower execution engines usually based on Chromium etc.

How to break spam bots?
-----------------------

Simple - put the HTML forms wrapped within JS code. Not the entire form, but the starting `` tag with all its properties.

Suddenly the spam bots are unable to find it. Less spam without too much work.
