Who are they fooling? Two paragraphs into the paper, the paper explains that the authors are expanding on their previous work. Since I know what work that is, I know who these folks are. Even otherwise, they have cited my papers several times -- and from the context, it's easy to figure out the authorship. So, not only do I know who wrote the paper, I can confirm it another way too.
Meanwhile, my review will have to correct one of their citations and a couple of their descriptions and that'll give the game away. They'll know who I am.
