In economics, there's a distinction between the normative and the positive. The former describes what ought to be and the latter describes what is. The concept seems relevant here. Operators ought not block mail solely due to some RBL data. Users ought not report legitimate mail as spam and those reported "spams" ought not be fed into blacklists. (I gave up on Vipul's Razor as a bad job once I noticed that this happens.) System administrators ought to focus on providing useful mail service—blocking spam ought to be an aftereffect. And so on. Not enough of these are. They sometimes are, of course, but it just takes a few system administrators with fucked up priorities to ruin it for the rest of us. Vixie's proposal won't help anybody.
