Would you tarnish your reputation for the sake of getting a PhD?

If the concern is that you don't need a publication in a peer-reviewed journal for your dissertation, then I would say it's not any worse than a PhD from NCU. 

Many "unaccredited schools", sometimes referred to as degree mills, require that their students take course, tests, write essays, dissertations and the whole thing looks pretty legitimate on the surface.  But if you actually look at the coursework it's clear that the material is at a 5th grade level.  Essays are written but does anyone even read them?  Maybe not.  Dissertations are written  but if you look at them they seem more like high school level writing and certainly not doctoral research.  You will hear people say "I worked hard for my degree!"  but the fact is, they don't even know what hard academic work looks like.  Don't be fooled.
