&quot;It&#x27;s different being a name on a list of millions of names and being aggressively singled out. The latter is effective, the former is not.&quot;<p>I&#x27;m actually aware of that, and carefully did not claim otherwise. I don&#x27;t question the effectiveness of that part of the strategy.<p>(I do question the ethics, but, well, I&#x27;m sure that doesn&#x27;t surprise anybody, including you. I say this mostly so I don&#x27;t get a followup from someone conflating my belief in its effectiveness with my belief in its ethicalness. But, yes, I would expect this to be effective. It&#x27;s also something that will get progressively less effective over time as more people do it, and I also think there is no chance that nobody else will do this, equally publicly. Privately I&#x27;m sure it&#x27;s already been done, of course.)
