Yes there are things you can do. Should you do it...No!
Why bother doing it? I've been banned off my school network because I downloaded a tool to let me send messages over the network, I didn't know I was doing wrong at the time, I didn't know it was violating rules and we weren't allowed to do it. But the teacher "claimed" that he made it clear not to do it and I got banned off the computers for a few weeks. I really don't want the same to happen to you, it's not funny to piss around with stuff that isn't yours, get used to it!
Network admins are unfair, even if you help them they treat you like you're a big trouble causer because it's their stuff. That happened to me even when I didn't mean any harm.
