I discovered yesterday that there were quite a few false positives in my wordpress spam filter. I’ve installed some additional tools to reduce the number of things in the spam folder so that I can review it more regularly, but generally, if you think your comment has vanished for some reason, email me. I do have a no asshole rule, but I will not enforce that by moderation- I will leave the comment up and then delete the body, rather than just make it silently vanish.
