How is this user able to add sources to an ID when they are already attached to another?
I thought the "loophole" for doing this had been closed. Or is this action still possible via ones Source Box, or by using the mobile app?
This user has attached this, and (it appears) many other sources like this (identical URLs) to more than one ID:
She is just going mad over the last couple of days in attaching sources to IDs that are totally unconnected to the individual in question, but the ability to add identical sources to multiple IDs in this way is particularly disturbing.
