Just a quick update about the current state of comment moderation on LFD. I've been receiving more than the usual number of spam comments linking to advertising sites and such, so I have put all posts on comment moderation, not just the usual pre-14-day posts. I'll leave it this way until spammites (not psammites, one of my favorite rock types) taper off. I'm thinking that maybe spammers/bots have ramped up their activity for the holidays.
The Fine Print: Names that link to adverstisements and websites selling things, instead of the more usual profile or blog, are automatically considered spam and will not be published or, if accidentally published, will be deleted mercilessly. Comments that contain links to advertisements and websites selling things are also considered spam, even if the comment seems "friendly." Sign-in names like "Mr. Low Prices" are dead giveaways that you happen to be a spammer. I will not publish any comments under any circumstances that link to sites selling research papers. If you think I should mention your website, blog, or name on this website - AND YOU HAVEN'T EVEN BOTHERED TO LINK TO MINE - uh, WTF??
UPDATE: Comments are back to the usual, with moderation only on posts older than 15 days. This state of affairs is subject to change without warning when I'm traveling or when I have poor or intermittent internet connections.
