An alternative is to give each subscriber only a small, fixed number of blinded tokens which he will use for the lifetime of his subscription to the list. When someone posts anonymously, they use up one of their tokens. Then, if the message was not abusive, a new blinded token is created, encrypted with the public key of the good-guy anonymous poster, and broadcast to subscribers. This way good anonymous posters will get to keep posting, while abusive ones will shortly run out of anonymous posting tokens.

Oops, ran out of tokens.... UNSUBSCRIBE cypherpunks SUBSCRIBE cypherpunks Lance OK now I'm ready to post more crap!
