在许多基于Web的应用程序中，用户有动机以假名注册多个帐户。通过这样做，用户可以从帐户发送垃圾电子邮件（这最终会导致该账户被关闭）;通过多次评级来扭曲在线评级（特别是，她可以夸大自己的声誉评级）;无限期地继续使用免费试用期的产品;对她在拍卖网站上出售的物品进行虚假投标;在组合拍卖中进行假名投标;从系统性能的角度来看，所有这些行为都是非常不期望的。虽然CAPTCHA可以阻止机器人自动注册多个帐户，但它们不能阻止人类注册多个帐户。似乎防止后者的唯一方法是要求用户提供在真实的世界中识别她的信息（例如信用卡或电话号码），但是用户不愿意给出这样的信息。
In many Web-based applications, there are incentives for a user to sign up for more than one account, under false names. By doing so, the user can send spam e-mail from an account (which will eventually cause the account to be shut down); distort online ratings by rating multiple times (in particular, she can inflate her own reputation ratings); indefinitely continue using a product with a free trial period; place shill bids on items that she is selling on an auction site; engage in false-name bidding in combinatorial auctions; etc. All of these behaviors are highly undesirable from the perspective of system performance. While CAPTCHAs can prevent a bot from automatically signing up for many accounts, they do not prevent a human from signing up for multiple accounts. It may appear that the only way to prevent the latter is to require the user to provide information that identifies her in the real world (such as a credit card or telephone number), but users are reluctant to give out such information.
