System and Network Admins are busy people. First years are interesting and sometimes entertaining, but generally don't shake the earth much when they make suggestions.

Some things on your college network are configured the way they are for reasons you may not understand, yet.

I suggest taking your discoveries or ideas to your CS professor. Explain what you think you found, demonstrate one of the flaws. Make it clear that you stumbled on this, and that you are bringing it to someone's attention. The CS prof can go to the network admin with a bit more authority and credibility than you.

You will find that the college work environment is much different than the k-12 environment. It isn't perfect, but at least it is usually populated by real professionals, not just wannabees.
