Yes, this is similar to preventing "hotlinking." I found out what that was...lol. Thanks for pointing me in the right direction Redlinemotorsports.
Here is what I was after


This code is for multiple referrer that you want to block

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} badsite\.com [NC,OR]
RewriteCond %{HTTP_REFERER} anotherbadsite\.com
RewriteRule .* - [F]

This code here is for one referrer to block

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} badsite\.com [NC]
RewriteRule .* - [F]

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} badsite\.com [NC]
RewriteRule .* - [F]

This code is useful to block sites that you do not want traffic from, and in my case, this is very helpful as I do not need traffic from a few sites.

I just tested this using vbulletin.org and it works great!
