You're probably being downvoted because more than a dozen comments on this thread mention Bad Blood (including the author), which was a bestseller this year and has been widely described and discussed across popular media. It's pretty easy to guess that the person you're replying to probably meant that.
a) As I specifically mentioned, "Bad Blood" is not the only title with this problem. Also, what if in this case we were talking of one of the dozens other books with "Bad Blood" in the title?
b) It is a bit sloppy to just throw out a title hoping that someone else in the thread will do a better job.
c) Unless we are talking of extremely well-known books (Dune? The Mythical Man Month?) I think it is better to always provide the author: to give an example, I personally dislike Tom Clancy, so if I see "Title-I-Am-Not-Familiar-With-Because-I-Am-Far-From-Being-A-Clancy-Completist, by Tom Clancy" I will just pass, while "Obscure-Title-I-Cannot-Recognize-Because-I-Read-It-In-Translation, by Jack Vance" would be enough to make me work a little to find out more.
