Technically speaking, constantly refreshing your scores page is basically participating in a DDOS attack against the MCAT server. I'm pretty sure they don't mind the neurotic refreshing, but it basically IS being an annoying user to constantly spam-refresh a website. I'd imagine the bandwidth/electricity bills on score-release days is off the charts.
I'm sure if any of your friends want experience dealing with DDOS security, working for the MCAT people would be like experiencing a real DDOS emergency every two weeks during testing season.
