I know I can configure htaccess to block referer spam of awstats, but shortcuts are always nice. Is there a wordpress plugin to block referrer spam on wordpress?

I just checked my numbers on statpress and they're screwed up because some wanker has been using prstorm or something else to crawl my site. I can't just glance at statpress - now I actually have to click through and analyze the numbers. I'm going to assume that radian6.com and justsignal.com are the same people (who are crawling the hell out of my site) because they're on the same server according to robtex.com.

And, btw, anyone know who these guys (radian6 and justsignal) are?

edit: I've already used wp-blockyou to block the listed IP's according to robtex but I don't think that will work. I'm including the URL to that plugin in case someone else needs to block specific IP addresses:
wordpress.org/extend/plugins/wp-blockyou/

OK, so I'm going to have to use htaccess to block radian6.com/crawler. Anyone tried this?

try this plugin buddy,

http://wordpress.org/extend/plugins/wp-spamfree/

u can set up and blocking any word, comment and IP address that visit your website...

i hope this plugin works with ur site...
