I can verify that because when George Bush became President, he was informed he could no longer communicate with his friends over his computer .. security purposes .. and also because the senior staff is required to not only log all their emails, but make copies of them.
If you're doing emails and visiting on FR, you would be required to record all that. It could prove embarassing later. It was one of Bush's favorite things he had to give up.
Do you suppose he can still lurk and that he is watching us? If so " I love you President Bush! You're doing a great job!
