Why did they ban the user rather than informing American intelligence and continuing to monitor the user?

They just gave up a source that could have provided info for years.

If I were doing this sort of thing, I would make certain to ban accounts that were too obvious while leaving ones that are subtle enough, so that the other side has less reason to suspect I am tracking their inputs and feeding them disinformation.
