It was discovered F&J employees were spying on the trialists's Discord group. One employee, who wishes his name to be kept out of any documentation, interacted directly with the trialists revealing his identity (sometimes trialists call him The Mole or The President). He is a nurse at F&J and working on the F&J dementia study. He not only participated in the Discord, but also met one of the trialists and gave her a phone, which he has used to contact the trialist a few times. He is interested in finding T, which is the reason he gave for revealing his true identity to the trialists.
He sometimes chats in the Discord group.
