Liz raised this today, and I've noticed a few others of my blogbuddies being invaded by anonymous spammer comments recently. There are some dolts out there who think this is a good way to promote themselves or their products.
I can't really see why Blogger allows anonymous comments at all, and have asked them:
ALL the (thankfully few) anonymous comments I get are spam of one sort or the other. I really can't see any justification at all for anonymity. They don't allow it on G+. Just banning it wholesale would eliminate most if not all comment spam, and harm nobody. What do you think?
