Referral Spam Bots

Lately our website has been receiving a lot of traffic from an automated bot from Russia. The referral is from a site called iloveitaly DOT co or iloveitaly DOT com. Standard HTACCESS edits have been thus far unsuccessful:

RewriteCond %{HTTP_REFERER} \.(ru|kz|in|ua)(/|$) [NC]
RewriteRule .* - [F]

# Block Russian Referrer Spam
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http://.*ilovevitaly\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*ilovevitaly\.co/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*7makemoneyonline\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*darodar\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*buttons-for-website\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*darodar\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*ilovevitaly.\.ru/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*ilovevitaly\.org/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*ilovevitaly\.info/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*iloveitaly\.ru/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*econom\.co/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*savetubevideo\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*kambasoft\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} buttons\-for\-website\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*semalt\.com/ [NC]
RewriteRule ^(.*)$ – [F,L]

 

We also tried/tested a javascript:

<script>

<script type='text/javascript'>

var blocklink = ['http://darodar.com', 'http://econom.co', 'http://shopping.iloveitaly.com', 'http://ilovevitaly.com','http://iedit.iloveitaly.co'];

for (var b = blocklink.length; b--;) {

if (document.referrer.match(blocklink[b]))

window.location = "http://google.com/";

}

<script>

After a lot of research several web developers developed a theory that these bots are not actually visiting the site. They are using Analytics tracking codes to trick Google into interpreting a web site visit. Any theories on what they are trying to accomplish with this black hat deception? As an aside we filtered them in GA but that too has proven unsuccessful. Are these fake referrals going to impact bounce rates and, therefore, effect our SEO/SERP
