Comment spam from Anonymous can be most entertaining. A couple of quickie reviews on my comic book blog has been getting a lot of anonymous comments. I have moderation turned on for comments, so none get published, but they're so flattering, if totally off-topic, which is difficult given the generalities. Here's one I particularly liked:
"A motivating discussion is worth comment. I do believe that you need to publish more about this subject matter,Literally, ninety per cent of what's posted in that blog is on the same subject matter and many, many of us blog about comics. In this case, flattery gets you nowhere.
it may not be a taboo subject but typically people don't speak about these subjects."
