The new Blogger commenting system has been in place in many of our blogs for just over two weeks . Some blog owners, who moderate using the new system, have started to notice a marked decrease in spam, hitting our Published, and Awaiting Moderation, queues, as the filters are trained. Other bloggers, who do not moderate, are observing the opposite. Since the new commenting system was started, my blog is getting twice as much spam as before. Oddly enough, both results were predictable.
