Well, that was fun. Google Recaptcha is known to not work hazy. I knew that, but it was free, which I liked, and it worked reasonably until last week.
Since last week the site's been flooded with comments related with sexual prowess and not software prowess at a rate of about 10 a day.
In response, I've closed the site to comments for the moment. Since my audience is small and not very post-minded, I don't think this will be a big loss for the short term.
Sigh. Go spammers.
