Well to be clear, I think a certain pattern of circumstances, while not particularly suspect on their own, may warrant followup investigation. Or put it another way, given the kind of place Parler is, the various already established links between factions of the American right wing extremes and Russia, it would not surprise me if the FBI were to open a counter-intelligence investigation into Parler. The difference here is that its not being put out on twitter for consumption, to metastasize in the wilds of our communal membranes. Sometimes twitter-ers need a good edtior that would say: "I need more before I publish this thing."
