Person A has an iTunes account and sets it up on a computer, with bunches of music files backed up from their iPod.

Then Person A gives the computer to Person B without thinking of the iTunes installation.

Eventually Person B or Person C, D, or E runs into the iTunes on the old computer, and plays songs and possibly rates them.

Meanwhile Person A is still using their iPod and has set up iTunes for their same account on a new computer.

Does the use of their iTunes music on the old computer affect Person A’s use of iTunes in any way? For example, will Apple think they are violating some contract about sharing music with others? Will Person A see “activity” or ratings that were actually done by people B C D E on their old computer? Anything else?
