Jon, the thing is that on Usenet there isn't a mechanism for stopping spam - once it's sent to the group then it's sent. Hence you either ignore it or you get the hell out of Dodge. Most people have taken the latter option, which is why Usenet is dying a death.

I don't often see "how dare you" posts on websites, I guess mainly bcos most users are smart enough to know the spammer doesn't give a crap and isn't stopping around to read the replies anyway.
