Someone should make a plugin that actively sends facebook false tracking information along with your own.
0. [page visited]
1. Does the page contain GA tracking ID?
no: do nothing
yes: add it to the database and replace it with another randomly chosen ID from the databaseCan you describe in more detail how google could detect that the GA identifier has been swapped and how to prevent detection?
But again, not an expert and I could easily be missing something crucial.
