I am starting my research on eliminating “semalt.com” from an Analytics report. One person suggests putting the following in your .htaccess file.

# block visits from semalt.com
RewriteEngine on
RewriteCond %{HTTP_REFERER} semalt\.com [NC]
RewriteRule .* – [F]

I haven’t tried this yet but I plan on it. The following is a link I started to use. I am sure there will be more to follow.

UPDATE:

I went to Semalt and registered some sites through their tool. I will try to update with the how it worked out.

I hope this helps someone out there…
