Reporting Hackers?

[Kim Kruse]

Has anyone had any luck reporting hack attempts to your webpage?
I can see them attempting to run scripts, from a certain IP address.
I can trace the IP address to who is registered for that address.
Frequently I then have a technical or other contact.
Is it worth my time to report the attempts? Can the originating IP addresses
be spoofed (i.e would I just be harassing an innocent party?)

Thx
Kim
