Last month showed a lot of new referral spammers. They seem to be coming primarily from the Ukraine. Bad black hat SEO companies continue to front as white hat and merely add these domains to robots that constantly hit your site. They have no link to you but when you go to see how someone might be linking to you – viola! Nothing.
If you are trying to build traffic with a company you should check this list periodically to see if your SEO company is using black hat robots to create traffic with referral spam. It eats peoples bandwidth and eats your money as it serves no real referrals.
Remember you have to just add this to your .htaccess before it calls your website and you will finally have referrals that mean something in your log files.
So grab the new july referral spam list and enjoy.
