I can't understand why you would go to all that trouble, Walter, although you seem to enjoy it! It's always interesting to see how different writers react to feedback. I only block someone who becomes a pest or who writes something so disturbing that I never want to hear from them again. I block people who insert links to their own stuff in the comments section of mine unless what they share adds significant value to the reader. It rarely does. Usually, it's someone looking for an opportunity to hitch their wagon to my star and their "offering" has nothing to do with my subject. The crypto bros are notorious for doing this.
