Of course you are being watched! Do you know who else is being watched? All of us! You are very high-profile compared to the rest of us, true, but who do you think it was who helped Albus with the initial spellwork that became the algorithms which track our wandwork? Do you think there isn't someone assigned to report on me? Do you think Marlene and Benjy, with their infamous tempers and their particular CV, aren't being watched? What about Remus? What about Aberforth?
We are all being watched. We need to learn how evade their gaze if we are to be effective, man!
