Mills come and go. They change names and locations but we're not very surprised when we learn that it's the same group of people behind the new name. Rather than create a list I'd invite you to use the search engine, keyword mill(s). You'll turn up a lot of threads that will not only include the names of the "usual suspects," but also their owners and some interesting background/history. In recent years, as regulations have tightened across the USA, many mills have moved to other countries or, at least they are marketing to other countries and so we are becoming less and less aware of this problem because it isn't poluting our own back yards. Here's an interesting example from 10 years ago - - - MIGS http://www.degreeinfo.com/monterrey-institute-graduate-studies/3435-migs.html?daysprune=-1 There are many other threads on this particular "school."
