wp-captcha Captcha System 1.0 for WordPress MU

Posted on | November 21, 2007 | 8 Comments

wp-captcha English Version

Introduction:

As many know, WordPress ® launched its system some time ago WordPress MU (WordPress Multi User) this system is a modified version of the original WordPress system, which lets you create a site where you can host a "myriad" of users who everyone can have one or more WordPress Blogs independent of each other. As an example you can visit the site EterBlogs

Issue:

The system allows anyone to register and create one or more users and also one or more blogs per user, the problem is that the registration system does not have any verification CAPTCHA * allowing any Robot (Boot, Spider or you name it) can access your page and create users and Blogs-Spamers. This lack of protection can cause many problems, since you'll have hundreds or thousands of blogs by advertising ( spam ) in your wordpress system.

Examples of Catpchas

The number of firms (mainly Chinese and American) working to make this type of illegal advertising are too many and it seems that every day they grow and above all creating new systems and robots that record softisticados blogs in public places, it which becomes more tedious and difficult task of managing and maintaining a site created with WordPress MU .

The problem is not only having to be eliminated and / or manually checking these blogs as spam and users as spammers. because if we can leave them there, but the increase in server resources can become quite worrisome, because the size of your database will grow enormously and exponecialmente, the number of queries to the MySQL database and also increase this obviously hard disk space, use of microprocessor and of course the bandwidth consumed by these junk blogs.

The solution:

Integrating Captcha system * is almost the perfect solution. the problem is that WordPress does not integrate this system as a free version of WordPress MU , in fact, even in his official sitema wordpress.com .

So after searching a plugin or hack that will integrate a captcha in wordpress mu and not finding any solution, I decided to program my own script captcha and some hacks to EterBlogs and make it available for those who want to integrate them into your wordpress sites, it is clarify that this script can be used on any other web system.

The script name is wp-captcha, as was originally written for WordPress MU and since the system can be integrated into any web page, either a CMS script or use a fromulario Plugin, I decided to keep the name but doing reference to P ublic W idespread - Captcha
