This is about the following question on Academia.SE. The OP in that question says that they have acquired some copyrighted data, which was made available to them on condition that they don't analyze it. They proceed to analyze it anyway, and discover something that ordinarily would qualify as good research. If they submit that research to a journal, can the journal legally publish it?
