It's not impossible for adults to do their job. A college professor who is the faculty advisor at the college newspaper or college radio station has actual responsibilities beyond blindly signing budget forms. Ever hear of "teaching" at a college? Maybe you have; maybe others have not.
I'm faculty advisor to a couple of clubs; for a long time I was advisor to CR. I take it seriously, but it's not my role to police all their activities. If it were, they'd never get anyone to volunteer.
Our college newspaper is typically 8 - 12 pages, 5 days a week during the semester. You think an unpaid faculty volunteer can afford to fact-check every issue? It would be more than a full time job for one person.
