See i will try to explain you the use of captcha....
Now people are preparing bots and they intrude the form by clicking on links abruptly and leading to increase in load on server....So to prevent it...Captcha is used....
Although now many crooks have trained their bots to do Character Recognition but still it is one of the way to prevent many of autosubmittion of records....
PS-Hope it was useful..If your problem is solved mark the thread as solved....
