Actually I beg to disagree on two pointsDifference was the activity was in the terms of the promotion, in that case such activity was not prohibited, more than one download of the toolbar in your case was clearly in violation of the terms, big difference. Surprised you cannot see that!
1. I didn't actually see anything in the T&C's that stated you couldn't download more than once, but rather PC would only give you points once. Not the same thing at all!
2. Having said this I think you'll find he didn't download more than once as it wasn't the download that triggered the payment.
