ie. Shut off your connection until you grovel and apologize profusely.
I've had a "server" (more like a PC) up and running since about '98. Granted, I'm not trying to do any commercial work (make a buck off of it) nor am I doing heavy amounts of traffic.
As for port scanning, sure they can port scan you. Heck, the rest of the world is port scanning you anyways, there's not much difference if they jump in. I'm not sure if its in an ISPs best intrest to do so since it takes CPU cycles to port scan all their nets. What I'd predict they do is they look at their router logs and see if there's abnormalities to their users' upstream rates. Then flag any questionable ones. They really don't need to port scan if their logs provide enough details.
