"But Father! But Father!" some of you are writing to me. "Why don’t you permit ‘anonymous’ comments? After all, this is the internet. You can’t really know who is posting. What difference does it make?"
I think Aaron Sorkin put it well:
Nothing has done more to make us dumber or meaner than the anonymity of the Internet.
I require at least some way for people to address each other personally and courteously. Having some name or handle helps.
