Individual characters are tracked via their ContentID, not their AccountID. The ContentID basically is the ID for the specific character, which allowed the tracking you were mentioning before. However the AccountID is a separate one which allows linking the ContentID to an account. I suppose you've mistaken these 2 different IDs which is why the misunderstanding came up in the first place. But yea, this is basically where the danger from playerscope comes from as it allows to stalk different characters of the same person as long as they're on the same account.
