Anyone here suffering from continuos spammers affecting your analytics? I've blocked more than 15-20 sites that continually refer spam visits to my site. I block them both from .htaccess file and with filters in Google Analytics. The problems is, new ones continues appearing every week, and it is becoming a real PITA to keep blocking them. Would it be really that difficult for Google to block them directly? Or do they just don't care? Sorry for the rant, but I'm frustrated with this problem.
