It used to be that, in order to have a more immediate discussion, you could leave commenting open on a blog.
Then spam comments begun to appear. At first they were an infrequent, minor nuisance, and a bit of clean-up once in a while was enough for keeping a blog clean.
Spam comments grew in frequency, which lead many bloggers to impose stricter moderation policies.
In this blog I started by leaving all comments open, but after a few years I had to impose moderation on all comments older than a certain date. Still, I tried to keep open commenting for the most recent posts.
But spam comments now have grown to the point that even for the most recent posts it is necessary to moderate all comments. I’m sorry for this, but I now have to direct all comments through the moderation queue.
I’ll try to post all legitimate comments as soon as possible, but some will end up being delayed – especially if they are written when I’m not at the computer.
