Ethical Limits to College Advertising?

No, I'm not attempting any plugs here. ;p

My wife spends approximately 2 hours a week conducting Law classes for students reading business administration at a local private college. It's not one of the more established ones, but neither is it an unknown institute. [What to do, the hubby might not be gainfully employed at some point in time in the future, hence got to find supplemental income for the family ;p]

She has been teaching for only approximately 2 months or so. But it appears that the private college has absolutely no ethical qualms about milking the fact that an Oxford graduate is teaching there. Apparently, they intend to run advertisements promoting the college to such effect.

Goodness! She's not even a permanent lecturer there, she's not teaching at a premium rate and not to mention the fact that she has yet to be paid for her classes to date. And the subject she is teaching is only an elective subject for the relevant degree programme.

I've always complained about the local private colleges stretching the ethical limits (for example, here and here) of marketing themselves and their educational programmes. Can it be stretched any further?
