A Hackers Newser violating a EULA? That'd be a first ;) As far as I know the EULA for them is use as you want for 30 days, then after that you have to reinstall it (or use an older snapshot etc).
Or use the re-arm mechanism (for XP, it gives a total of 120 days). The desktop background after install of those VMs is a text wall of how to do that :)
