向发送消息者收费以进入您的收件箱

Make people pay to get into your inbox

**Captchainbox** 是一款收件箱管理工具，旨在通过要求陌生发件人证明其身份，从根本上杜绝人工智能生成的冷门垃圾邮件。 **工作原理：** * **基于信任的过滤：** 该服务会分析您的电子邮件历史记录，以建立信任联系人列表。来自这些来源的邮件将正常送达。 * **验证门槛：** 当陌生发件人向您发送邮件时，其信息会被静默存档（绝不删除），并收到一条验证链接。 * **意图证明：** 为了让邮件进入您的收件箱，发件人必须通过验证码（CAPTCHA）测试或支付少量费用。这些费用随后将捐赠给慈善机构。 * **隐私至上：** Captchainbox 仅根据发件人的元数据进行过滤；它从不阅读您的邮件内容，确保您的私人对话保持安全。 **主要功能：** * 兼容 Gmail 和 Outlook。 * 包含对日历邀请的保护，并支持基于抄送（CC）的介绍方式。 * 提供 5 分钟快速设置及 7 天免费试用。通过将负担转移给冷门群发机器人，Captchainbox 帮助用户重新掌控时间和注意力。该服务每月收费 5 美元，为那些深受大规模定制化 AI 骚扰困扰的用户提供了一种自动化且注重隐私的解决方案。

Hacker News 社区近日讨论了一款名为“Captchainbox”的工具。该工具旨在通过为陌生发件人设置“工作量证明”门槛，来应对人工智能生成的垃圾邮件潮。该服务会根据用户历史记录，自动将已知联系人和交易域名列入白名单。来自未知发件人的邮件会被转入存档，并要求发件人完成验证码或支付少量费用，通过后方可进入用户的主收件箱。开发者表示，支付所得将捐赠给电子前哨基金会（EFF）和互联网档案库（Internet Archive）。社区对此褒贬不一。尽管用户认可“AI 生成的垃圾内容”泛滥这一问题，但许多人认为强迫发件人进行验证在本质上带有排他性，甚至显得有些傲慢。一些评论者建议采用更温和的方案，例如基于联系人列表的自动筛选，或直接将陌生邮件归档以供稍后查阅，而无需与发件人交互。此外，还有人担心如果强制性联系信息（如德国法律要求的 Impressum）被此类机制屏蔽，可能会引发法律层面的访问障碍。归根结底，这场讨论凸显了在应对海量电子邮件压力与保持沟通渠道开放、便捷之间所存在的矛盾。
