The big problem is, of course, the fact that a PC is so easy to come by. If someone is using stolen credit cards, likely it wouldn't be above them to get another one. The service does little more than modify the user's installation, which likely is something that won't be cross platform and would be wiped clean by a fresh install or a moveto a new machine. As far as most online stores are concerned, a new credit card might as well be a new person.
