If you post a legitimate comment on an article here and the system rejects it, sending a rather unpleasant email I think (default/built-in content, not mine), please let me know via email (jbala at jimbala dot net).
I’ve recently installed new comment spam software and I am still adjusting its settings. Recently, several IP addresses showed up in the blacklist and I didn’t receive any notification that those comments had been rejected/deleted; it’s supposed to notify me when any comment post is deleted.
If your comment, not being spam, was rejected/deleted, I apologize for the trouble. I’ve significantly decreased the software’s sensitivity level but I still don’t have any real idea what will or won’t trigger a automatic rejection/deletion. But hopefully it will behave more nicely now and still catch most or all of the spam comments.
