I suspect it's overkill and drastic to hope that aol.com, netcom.com, prodigy.com (well, maybe not them), and others will hold their subscribers to a particular code of behavior before the fact. None of them are notorious for not caring after the fact, and I wouldn't hold them to a higher standards of preventing this sort of stuff than I'd hold myself to. I appreciate your frustration, but it's a bit harsh to shoot the common carrier. (No, legally, they aren't common carriers. They should be, but....)
