使用 .htaccess 阻止引荐来源网址垃圾邮件
我们的论坛经常受到试图自动注册的自动机器人的攻击。
我们可以从错误日志中看到一个例子
[2011 年 4 月 3 日星期日 14:04:46] [错误] [客户端70.183.110.133]文件不 存在： /home/spoilert/public_html/forum/++++++++++++++++++++++++++++++++++++++结果：+验证码+解码+(23+尝试);+注册+(注册+仅+模式+is+ON);, 推荐人： http://forum.spoilertv.co.uk/++++++++++++++++++++++++++++++++++ ++++结果：+验证码+已解码+%2823+尝试%29;+已注册+%28注册+仅+模式+is+ON%29; [2011 年 4 月 3 日星期日 13:45:54] [错误] [客户端70.183.110.133]文件不 存在： /home/spoilert/public_html/2008, 引荐来源：
我已经用此代码更新了我的 htaccess
SetEnvIfNoCase 引用者 “^http://(W)decoded.*$”已被禁止
否定 来自 env=banned
它“应该”拒绝任何带有解码的单词的引用链接，但它似乎不起作用。我似乎仍然有一些机器人使用相同的 URL，所以它似乎仍在发生。
Our forum gets targeted a lot by automated bots that try to register automatically.
We can see an example here from the error log

I've updated my htaccess with this code
SetEnvIfNoCase Referer
"^http://(W)decoded.*$" banned
Deny
from env=banned
It "should" deny any referrer link with the word decoded in it but it seems that it's not working. I still seem to be getting a few of these robots getting through with the same URL so it seems that it's still happening.
