Perverse incentives? Conflict of interest?
I just received a request to referee a paper. I accepted (electronically) because the editors of the journal in question are good friends, and I want to help them whenever I can. But after accepting, I got access to the paper, and I found that the author cited me. In our brave new world in which one's value as a scholar is judged by "metrics," I now have a strong motivation to approve publication of this paper, since the value of one's own publications is often judged by how often they are cited. I hope I can avoid evaluating the paper based on the fact that "Hey, here is someone who cites me: they should be published!" But can I really do so? I don't know. And note: I was asked to referee in this case precisely because I was cited in the paper in question: since I was cited, I must know something about the topic being discussed. I only bring this all up to point out that the peer-reviewed system is far from perfect. I have no better suggestion...
