Capcha Codes Are They Needed?

Many sites use Capcha Codes as a means to keep their site somewhat free of spammers. This code can be both helpful and bothersome at the same time. Capcha Codes should be in place when a person logs into their site but is it really needed every time you do something on a site? Take myspace for instance, many members are considering leaving the site because of the Capcha Code. Myspace is a place for communicating, meeting new people and socializing. Let's say someone posts a house party in a certain city, spontaneously in 3 hrs but limits the number of invites for instance. Everyone that doesn't have anything to do at this time within the area decides to go hook up with their friends on myspace. They quickly try to contact the party thrower on myspace but find everytime they go to email the Capcha Code is incorrect, not accepted or the event is full. Perhaps another way to signify the use of myspace for email or comments to others on the site is to make the sender put more than a "nice pic" or "where can we meet?" reply email as a response to something that they have seen on the site.

Yesterday, there was an article written up in the Washington Post in regards to spammers cracking the Capcha Codes that were put in place by the 3 Big Mail Servers on the internet. Microsoft, Yahoo and Google have all used Capcha Codes as a way to deter the spammers who bog down their mail servers with senseless offers of items or services that people don't want. These spammers both human and computer generated, have broken through some of the Capcha Codes allowing spam email to flood members mailboxes. They create numerous ficticious email addresses to send all sorts of spam email through the internet that somehow manages to bypass the spam email filters produced for this particular reason. Something different perhaps can be put in place once someone invents it but to quote the last statement, "Making tests harder for the computer, makes it harder for humans as well." Anyone have any suggestions? Does having Capcha Codes on sites bother you?
