Just this past weekend I added mod_rewrite commands to give this crap
a very short error page with a custom 491 response code. (I use a
send-as-is page for the error page to be able to specify the response
code.)
So far only one URL is being hit, so my RewriteRule is specifc to just
that one. So far I have just six RewriteCond for %{HTTP_REFERER} ORed
together to block the crap without blocking legitimate linking from
search engines. I'm sure I'll need to add more RewriteCond as time
goes by.
