Google's spam filter has pretty much given up, it looks like. Spam comments on this blog started popping up like crazy a couple months ago. I turned comment moderation on so I could stem the flow before they got on the site but my continuous "Mark as spam" work has done nothing to improve the filter. So now there are captchas that have to be filled out before comments get published. Sorry about that but the moderating thing was getting old. Way to go spammers, you've ruined it for everybody!
