title: How to Block Spam Referrers like darodar.com from Accessing Website?
body: <p>I have several websites that get daily around 5% of visits from spam referrers. There is one strange things I noticed about this referrers: they show in Google Analytics, but I cannot see them in my custom designed table where I insert all the visitors to the site, so I think that they only manipulate the GA code, never reaching the site itself.</p>
  
  <p>If you follow their link, they redirect you to some affiliates link.</p>
  
  <p>I don't know whether they have impact on my SEO/SERP, but I would like to get rid of them. May I do that via <code>htaccess</code> file?</p>
  
  <p>One peculiar aspect is that I get visitors from different forum like pages. E.g.: <code>forum.topic221122.darodar.com</code>, <code>forum.topic125512.darodar.com</code> etc., so I would like to block the full <code>darodar.com</code> domain. </p>
  
  <p>Besides <code>darodar.com</code>, there are also <code>econom.co</code> and <code>iloveitaly.co</code> that are bothering my stats. Can I block them all from <code>htaccess</code>?</p>
