If FB wanted to show the researcher that they were really, ALL-CAPS serious, then they would talk to him directly as in &quot;You&#x27;ve got stolen data and we&#x27;re going have the FBI arrest you, seize your computers and put you in jail ruin-your-livelihood if you don&#x27;t stop&quot; serious.<p>So I still don&#x27;t see how calling the guy&#x27;s boss trumps that in terms of scariness. Because if I&#x27;m the wronged party (i.e., FB), that&#x27;s what I&#x27;d do <i>if I couldn&#x27;t resolve it amicably</i>.
