Those who comment here may have noticed a delay in the appearance of their comment. We’re dealing with an especially heavy volume of spam comments and have been trying to adjust the filter settings. For those of you who subscribe to the comments feed via RSS, we apologize for the spam comments, most of which is pornographic, that are getting through the filter. If we set the filter too high, valid comments are caught in the filter, if it’s set too low, the spam gets through. We appreciate your patience as we find the right balance.
