Email, I suspect.

These days, though, the spam has gotten so bad that I'm filtering it out directly at Nyx, using SpamAssassin. Since it uses Bayesian filtering as well as spamish rules, I can train it (once the admins set it up) to recognize things that I want to read, as well as things I don't want to read.
