Here's the deal
I don't moderate comments. I don't get enough to worry about and almost all have been on point and respectful. I've noticed that I am attracting a few more spammy comments and at least on company that sells a NSFW product has posted numerous spam comments. For now, I am going to leave the situation alone. Rather than moderate comments, I'll assume everyone understands that anonymous comments don't come from me. If it does get worse, I'll move to moderating comments. Unless anyone can tell me whether I can block comments from a specific visitor in Blogger. That would be the better solution.
