About five days after I decided to have non-member comments be moderated, I've changed my mind. From now on there will be no moderation (it was a pain for me to do, plus it disrupted the spontaneity of comments). Instead, I've put in place a high-tech anti-spam feature in which people who submit comments have to first type in a word displayed in a box. Members won't have to do this. Hopefully the spammers won't be willing to do this. If they do it'll be a complete waste of their time since I'll promptly delete their spam.
