Have you ever actually done that?  In my experience, most ISPs won't
give that information or talk to you unless you're a law enforcement
person with a subpoena from a court in a country that the ISP
recognizes, and there isn't any language barrier, and you've contacted
them soon enough for them to preserve whatever logs they may or may
not have.  Even then, there is a fair chance that what you'll find
isn't a perpetrator, but a virus-infected computer with a hidden proxy
or botnet running on it, or something similar.
