I don't know anything about Spamrats, but one of the ways this happens is 
that some users are deciding to mark Email as spam when they no longer 
want to receive it, instead of unsubscribing.  So it may even be a user of 
this very ISP which has done this.

What I recommend doing is finding out if this ISP has some kind of a 
feedback loop, where you can get notification of spam reports instead of 
them being acted upon.  Spamrats might also have such a loop.

Unfortunately, to keep delivery alive to everyone, you've got to be on 
everyone'se feedback loop, and some people have fairly stringent 
requirements (e.g. Yahoo requires DKIM or SPF).
