Then their stash will be confiscated
Presumably by "then" you mean "after authorities review the complaint, decide it's actionable and worth investigating, investigate it, identify the perpetrators, bring charges, and secure a conviction". Because we are, still, sort of, in part, a nation of laws.
I wouldn't recommend holding your breath waiting for any of these confiscations.
