For the rest: it could work quite well a lot of the time but at least some of the time it will lend a false sense of division to a single user no matter how it's done. With an IP anonymizer and two or three or four... browsers it would be pretty easy to appear to be a gang when it's really just one. And the more specific/careful the technique for keeping the AMs separate, the more likely a single anonymous monk will <accidentally appear to be two or more. :|
Yes, this may well create a "false sense of division". As I said in another comment, I'm not worried about that - this isn't intended to cover all possible cases. This is intended to cover a significant majority of cases.
