If your comments are not showing up: We use WordPress.com, and its optional spam filter, Akismet. I have no control over what Akismet flags as spam. Ordinarily it is very good, but I just looked in the spam folder and noticed that an unusually high number of legitimate comments got accidentally flagged as spam. I freed those I found from spam-land (which should help those of you who are serial commenters), but this problem may recur. I don’t have time to check the spam filter very often, but I will try to glance at it now and then.
We also filter for certain abusive or profane words and for people with a history of writing abusive comments (personal attacks on other people).
