It's also illegal as all hell, but I'm sure no one cares.
Depends on your jurisdiction, doesn't it?
Not after the WIPO changes went through about 4 years ago. In Germany they can kick you out of Uni, should they find out. In my company several people lost their job trying to pull that stunt.
Just saying.
Not calling you out on this, but I struggle to see how someone at a University would be caught. Maybe thrown out if they did, but finding you would be the hard part. I access possibly hundreds of articles a month as part of my degree course, unless I started spending more time selling articles than I do studying I find it difficult to believe the IT department would track me down out of an institution of over 30,000 people.
EDIT: So on second thoughts, I suppose I could probably offer a similar service.
