I'm pretty sure the Rampires selectively turned individuals in critical positions, so they could have their people in those critical positions; so fooling colleagues seems to have been Rampire SOP.
At least some effort to keep friends & close family fooled seems obvious, even if it's just long enough to enact breakups/etc (or turn them, in turn (but that'd be an every-widening pool of complications)).
I don't think Jim has ever explained it in detail, but I presume he's considered his setting in far more depth than he has put out in public.
No, he hasn't, however I might add has he ever shown anyone from the Red Court with human friends and family once they have fully turned. Bianca thought she loved her human secretary, but as it turned out mostly as a source of food. Kind of like the relationship people have when they keep a pet tiger. They forget that a tiger is still a tiger, a wild animal, until one day they get attacked.. In a fit of rage, after Harry forces Bianca to revert to her real form, she killed her secretary, she was in full "bat monster form when she killed her "beloved" secretary.
It doesn't seem relevant to the OP's issue, and I haven't seen anyone disagreeing with you, but you keep returning to re-emphasize it.
I do, because it is an important point! Also I think you are confusing White Court Vamps with Red Court Vamps, while both are vampires, they are nothing alike.. WCVs appear human and in most ways are very human, RCVs are not.. RCVs can put on a human mask, and act human, but there is nothing human about them as we saw when Harry pushed Bianca with his sunshine hanky..
