Some blog owners don't understand the need to identify themselves , when commenting on our blogs. We see an occasional question, in Blogger Help Forum: Get Help with an Issue , about comment authentication. Why, if I've selected "Anyone - including Anonymous Users " under comment settings, for "Who can Comment?", do my visitors complain of having to login? This blog owner, like many others, does not understand the Blogger spam mitigation policy, in Blogger Comments.
