A Captcha system was applied

Everyday i received about 80 spam comments at my blog. It makes me really annoyed because I must take a look to see if there is a real comment in that mess. As consequence I am tired of reading all of them and therefore some real comments which are false recognized may be deleted too. So today I decide to apply a Captcha system at comment section to reduce spam. I hope that most of spammers will be stopped by this system.

A CAPTCHA or Captcha (it is a contrived acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart.”) is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. The process usually involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. Thus, it is sometimes described as a reverse Turing test, because it is administered by a machine and targeted to a human, in contrast to the standard Turing test that is typically administered by a human and targeted to a machine. A common type of CAPTCHA requires that the user type letters or digits from a distorted image that appears on the screen.

The captcha system which I used is Simple Catpcha. It is easy to use, just install and everything works. There is a small problem that we can not install it through available Plugin Browser/Installer functionality of WordPress because the archive of installation has a false structure. It has a folder too much. Therefore I recommend that you should download the installation packet and install it manually.

I hope this captcha will help me preventing spam comments. Because during installation of this plugin, I must delete more than 4000 spam users with more than 20000 spam posts at the forum of my high school classh. This forum is phpBB forum and activated with a captcha system but I think the captcha system was broken.
