You may notice from time to time that I turn off comments for a post that is older than seven days old. While I normally don't get comments after seven days anyway, the reason I do this is there are spam bots that like to promote cheap pharmaceuticals and other such filth in my comments. It seems that turning off the comments for a week or two fixes the problem temporarily. There are spam blocking utilities like captcha support and such if I upgrade to the new subtext version, but it seems to work if I turn off the comments for a while. So heads up, the comments are now off for posts seven days old or more.
