It's not about preventing 100% of spammers. Nothing can (without sacrificing a great deal of user friendlyness) and nobody claims it will do it.
It's about discouraging most of the human ones and making it harder for automated systems to bypass it. And quite frankly, even the simpliest forms of captcha will discourage many of the human spammers. Bottom line is that using a captcha is not useless at all and it does prevent some human and automated spammers from abusing a service.
