Looks like I’m not the only one who has been getting referrer spam from phiberweb.com. Two lines in my .htaccess and he now gets a 403.
RewriteCond %{HTTP_REFERER} phiberweb\.com
RewriteRule .* - [F,L]
Mark Pilgrim is also very keen on killing rude bots.
While I’m at it I gave kooqoo.com the finger, since their RSS crawler incorrectly says their site is referring to me. It doesn’t. Bye bye.
