帐户电子邮件验证重要还是不重要？
在基于社交/用户的网站上，需要用户注册，为什么验证帐户（通过向电子邮件发送确认链接）很重要（或总体趋势）。如果在注册过程中使用了良好的验证码系统（例如recaptcha），是否还需要使用电子邮件验证？ 它有什么优势？
On a social/user based websites, where user registration is required, why it is important(or general trend) to validate the account (by sending confirmation link to the email). If during the registration process, a good captcha system (for example recaptcha) is used, Is there still need to use email validation?
What advantage it gives?

电子邮件确认可以防止不法分子恶意向其他人订阅包含他们不感兴趣内容的网站。
任何需要注册的信誉良好的网站都将确保电子邮件地址的所有者确实想要订阅/注册其服务和内容。
这是通过包含确认/验证链接的电子邮件来验证所提供的电子邮件地址是否被合法使用来完成的，必须单击该链接才能完成注册。
此类注册系统通常最多允许 24 小时完成验证，否则待处理的注册将被删除。
这允许意外或以其他方式收到其中一封电子邮件的收件人忽略虚假/无意/错误的注册，并在必要时在有恶意证据的情况下联系网站所有者。
Email confirmation prevents miscreants from maliciously subscribing other people to sites with content they're not interested in.
Any reputable site that requires registration will ensure that the owner of the email address actually does want to subscribe/register for their services and content.
This is done by verifying that the supplied email address is being used legitimately by way of an email containing a confirmation/verification link that must be clicked to complete the registration.
Such a registration system would typically allow up to 24 hours for the verification to be completed, otherwise the pending registration will be deleted.
This permits recipients who accidentally or otherwise receive one of these emails ignore the fake/unintended/mistaken registration and if necessary contact the site owners if there is evidence of malicious intent.
它验证电子邮件帐户：检查提供的电子邮件是否确实是真实的电子邮件，以及创建该帐户（并知道密码）的用户实际上可以使用该电子邮件地址。
It validates the email account for one: checking if the email supplied is actually a real email, and the user who made the account (and knows the password) can actually use that email address.

Apart from what Kev already stated, the e-mail verification can prove useful for two additional reasons:
