Are all unaccredited Universities Diploma Mills?

[Virtual Bison]

And if the answer is no, than how can you tell the difference?

I personally believe that there is a difference. It has to do with how much work, if any is required. A phony baloney college will not require any work whatsoever. Just send a check or give a credit card number and voila your diploma is in the mail. I even heard of some so-called schools which will provide your employer with transcripts and phony references.

Obviously, this is unethical and I would never a do business with any "institution" which does business that way.

What does piss me off is that so many bogus universities make the rest of the unaccredited institutions look bad.
