one final thought. given that this customer is clearly a total dick, you might still try to be accommodating and give him a clear and documented warning that his behaviour is unacceptable and that, if it happens again, you will cancel his account. if this *does* end up in court, it will at least show that you *tried* to be reasonable (even though you really don't need people like this as customers). in terms of actually going to court, you have to ask what he would be demanding in terms of damages, and it's not clear he can ask for very much. IANAL, but i can't see *any* grounds for him demanding some massive settlement or punitive damages since all you're saying is that you don't want him as a customer anymore. and, unless you did agree to a long-term contract with him, you should be able to boot him off. (he certainly can't claim abridgement of free speech or censorship given that there are an infinite number of other ISPs he can use.) again, as others have pointed out, the spam legislation you were referring to is used to identify when you can *prosecute* someone over spam. it has nothing to do with your situation. you're not trying to collect damages. you just want to get rid of the dick. rday
