From the beginning of this blog, I've been as liberal as possible about comments. Anonymous comments are welcome and I have not insisted on moderation before the comments appear. In the past two weeks, though, there has been a major spam attack going on with, last weekend, over 100 postings, most of which never showed up because posts over two weeks old did have to be approved. But the attacks have continued.
I am regrettably shifting, at least temporarily, to moderated comments: usually I should be able to approve legitimate comments soon after you post them, but it's much more efficient if the comment appears only with my approval instead of my having to take down dozens of spam posts every day.
I hope I can relax this soon. Your legitimate comment will be approved as quickly as I can, but there may be delays on weekends.
