A Little Moderation
I have been having a mild spam problem, "comments" with links in them that have nothing much to do with what they are supposed to be a comment on or are in a language, I think Chinese, that I cannot read. Removing them by hand is a pain, so I have just modified the blog settings to require any comment on a post made more than thirty days earlier to be approved by me before it is posted.
The reason for this post is to explain that, if you comment on an old post, it may be a day or two before I notice your comment, approve it, and it appears.
