a colleague of mine notes "phd" in her credentials, and on her website notes her education. the place she got her phd was an egregiously bogus diploma mill that was shut down in several states for being fraudulent, has gone out of business, and is facing lawsuits from many grads who cannot use their credentials because they came from an unaccredited (and widely discredited) "school." i am conflicted about what to do. should i gently remind her that leaving this up on her website opens her up to criticism and perhaps loss of opportunity, e.g., future potential clients will see that and decline to use her services? or just mind my own business and let it stay up there and make her look bad?
