If someone scans several ports, I usually do report it to their ISP,
sending them log excerpts that include the time they occurred and also my
time zone as reported by my computer.  The ISP would probably warn the
customer and even terminate the customer's account if they believe the
customer was up to no good.

I usually do not report attempts to connect to single ports.
