I once (accidentally) took down Netcom with a fork bomb. Not just one node, but all of them. When I tried to login again after they rebooted everything, I found that my account had been banned. I got a NOC admin on the phone and apologized for my mistake, but also asked him why they did not enforce a maximum number of processes per user (via ulimit). Apparently they had never thought of doing that. He thanked me and my account was restored immediately.
