why challenge/response email systems are bad

I always advise people against using C/R systems since they don't help solve the spam problem and often just annoy people. I've been too lazy to write something up with some good information. Thanks to Karsten Self, I don't have to. He has an excellent article Challenge-Response Anti-Spam Systems Considered Harmful
