In this post I'm going to explain a way of waste the RAM memory instaled in the computer, which affects to a lot of users.

The web pages increasingly receive more SPAM of programs that automatically fill the forms of the webs. To avoid it, appears the annoying CAPTCHA ("Completely Automated Public Turing test to tell Computers and Humans Apart").
