I call this a *credibility slide*. The idea is if you have something, lets say a vaccine, that does in fact kill a bunch of people, how do you cover that up when you can't supress word of mouth efficiently enough? You put one person out there prominently, claim they died. And then *gently* walk it back later. If you only post hearsay or 'credible' sources to the side of the aisle you're targetting the effect is simple: they become more certain its a lie. Meanwhile you provide the same soft 'evidence' of her being *alive* to sites frequented by the other side of the aisle. And as long as one side is pro-authorities or on-message for the official narrative, then bada bing bada boom, you've divided the public and cemented that conflict over what is even real. All while the injections are actually killing people.
