Theftwarner JS is a library written in pure JavaScript. It requires no additional files or libraries like jQuery or Prototype JS. It is very easy to setup and use and it integrates nicely into any kind of website, CMS (like Wordpress, Joomla) or e-commerce platform (like Magento, XT-Commerce).

Theftwarner JS foils the content theft by removing the copied text. Instead it shows a fully customizable warning message when the copied text is pasted somewhere else.

Because Theftwarner JS is customizable, you may also define at what length it should start removing the text copy. This way your visitors are still able to copy links or E-mail addresses from your website.

Theftwarner JS also comes with source code detection. If you are a software developer and want to allow others to copy and paste your source code snippets, Theftwarner JS makes sure that those copies are never removed.
