I no longer do that. If the FBI wants to know who you are, let them do their own homework. Neither am I continuing to communicate with dumbasses through the offices of courtesy. If I exchange email with you, and you are a dumbass, it is only to throw the FBI off the scent.
If you are not a dumbass, communicating with you will throw the FBI off the scent anyway – because they think you are one. Dumbasses.
