我制作的一些网站存在垃圾邮件发送者的问题。我已经确保消息在发布之前必须得到批准，但最近情况变得更糟了。
在所有垃圾邮件之间我只能看到一个链接。据 称，所有 IP 地址都geoiplookup来自中国（还有一些来自乌克兰）。我想“嗯，这很容易。只需屏蔽这两个国家。无论如何，这是一个荷兰网站。”。问题是GeoIP扩展没有安装在有问题的共享主机上。
我更喜欢这种解决方案，而不是像 Captcha （反正没人能读到那些血腥的东西）或需要注册和登录之类的东西。我也不想依赖其他网站，因为它们可能会离线或窃取信息。
还有其他方法吗？这个国家是我能找到的唯一链接。用户代理同样是随机的，因此 IP 地址也属于同一 2 个国家/地区。我已经实现了阻止用户在 Tor 网络上发帖的功能，但他们似乎没有使用 Tor。
我知道我可以使用 Javascript 获取某人的位置，但那是客户端，很容易被禁用。
可能重复： 如何阻止来自中国的请求到我的应用程序？
巧合的是，这个问题上的 OP 也有同样的问题。建议执行以下操作：（感谢 Lawrence Cherone）
您可以尝试在 .htaccess 中阻止整个中国 IP 范围
