Henceforth, here is my policy, which I have now posted in the blog sidebar:
Comments should be signed. If a technical glitch forces you to post as an anonymous user, please include a signature, which may be a fictitious name to protect your privacy. I will hold your comment and release it for posting after I receive an email from you claiming the comment and containing your real name. Otherwise, I reserve the right to discard your comment after twenty-four hours.
