Yes, it is dangerous stuff and so far no one - as far as I know - has started to investigate whether Peter Strzok (sic!) was acting on ideological reasons only or if he was paid by for instance Fusion GPS or foreign a tors. According to an albeit conspiracy theory site par excellence Strzok was enjoying a rich life-style somewhat above his known income.
I have no idea if Strzok was living above his means or not. I would only say that this is how the arch-traitor and Soviet mole Aldrich Ames was caught and it was not in the act of passing documents to the Sovs; on an otherwise decent but not wealthy income as a CIA official, Ames had multiple high end foreign sports cars. If in the event that Strzok could be shown to be living above his means (and I have no idea that he was or was not) then it would make for a very interesting issue to investigate.
