Many moons ago I set comment moderation in place that required me to approve every comment before it could be read by the public. I did this at the time because of a number of troll-like comments that were being left by - surprise, surprise - anonymous readers.
Over the past several weeks I have been receiving a great number of spam comments. Because I have grown tired of policing spam comments, I am now requiring all commenters on this blog to sign-in (you can still comment anonymously, after signing in, if you so wish).
I'm sorry for the inconvenience and the annoyance factor this may cause, but as most of my regular commenters do so on Facebook, this shouldn't post too great a difficulty to anyone.
