Incidentally, those who are having moral issues with this hack (as opposed to legal issues) should glance at this thread:

It makes it clear that Jelsoft are willing to enforce license terms to the letter, even against someone harmlessly using a "test site". That's fine - it's their right, and it is clear in the license agreement that one cannot do that. But I don't see a moral quandry here should I find myself in a position where I might want to do something permitted by the license but which is against Jelsoft's interests.
Licenses work both ways.
