This made me think about a few students that I know who used their university resources to cpu mine certain altcoins for quite a long time. It actually surprised me that they have had their mini farm running for at least three months, before they were forced to stop and got an official warning as result. I can definitely understand why steps are taken to prevent mining to take place within the borders of in this case a mall, universities, businesses, hospitals, etc. If being very strict, it could even be seen as theft of resources in the worst case. Other than that, the article got spiced up by using the term banning in order to make it look more interesting.
