I must say I'm not particularly thrilled about the tactics employed by SpamCop. At a university it is sometimes difficult to control every single thing that everybody does on campus, unless of course perhaps if this was a complete authoritarian state. We try hard to control and minimize spamming events, but alas, sometimes they happen.
Just recently we discovered we've been tagged by spamcop. Since the spamtrap is "secrete", there's no way to know what incident triggered this event, which makes it pretty damn difficult to track it down to try to deal with it. Furthermore, a site has only one chance to delist their server. After that, it's a permanent block. So, if we can't tell what source is a problem, only have one chance to delist--EVER--seems to me we're pretty screwed. Lovely. Amos
