Maybe their artificial intelligence software honed in on QAnon, as a key network in spreading information detrimental to the Democratic Party, during the election (traffic analysis). We know that they have been using AI to analyze users and meme flow, and they have been searching for ways to influence the election.
Maybe they particularly want to disrupt that network now, because of the declassification of Russiagate documents, to slow the development of any crowd-sourced insights, or their communication to the wider electorate.
It might have been part of a planned information war approach during the election generally, or iprepared as a contingency response to control/mitigate emerging scandal.
