In the past month my comment spam has increased exponentially, which makes it harder for me to go in and rescue the occasional comment from an actual human being that WordPress has, for reasons known only to it, decided are sufficiently spam-like to punt into the spam queue. So: If you tried to post a comment and it doesn’t show up automatically, if after a day (24 hours) it does not appear:
1. It probably went to the spam queue and was deleted (sorry);
2. If you feel like it try to repost it and if it doesn’t work, send me an e-mail and I’ll try to go in and retrieve it.
Note that most of the comments that don’t immediately show up go into the moderation queue; I get an e-mail about those and try to free them as quickly as possible. But once in a while, off to the spam queue they go. There does not seem to be any rhyme or reason to it. The ways of the WordPress spam filter are mysterious (although, to be fair, in general is does an excellent job).
Anyway, as always, please note that unless I have specifically told you otherwise, if your comment does not show up after you post it, it’s due to automatic filtering and not me hunching over the comment thread, moderating you ahead of time. Honestly, I don’t have the time for that. So in almost every case, if your post doesn’t show up immediately, don’t get paranoid. It is almost certainly not personal.
