如何阻止引荐来源垃圾邮件

Question

I am using NGINX and one of my site is suffering from referrer spam.

I followed the NGINX wiki, and I found this but after using the code, it is blocking my site. Is there any solution? I have also tried using this code but it didn't worked

if ($http_referer ~ "spamdomain1\.com|spamdomain2\.com|spamdomain3\.com")  { 
return 444;
}

I want to block the domain from where I am getting referrer hits.

Answer 1

I would use a map.

# at the http level:
map $http_referer $drop_referer {
    default 0;
    ~spamdomain1\.com   1;
    ~spamdomain2\.com   1;
    ~spamdomain3\.com   1;
    # ... (put these in an included file if there are many)
}

# in your server stanza:
if ($drop_referer) {
    return 444;
}

We began working on our internal tool ReferrerSpamBot that helps adding the dynamic filters to your Google Analytics account and also we want to develop a module for nginx in the future. Check out the project on GitHub
